Database Migration Option (DMO) of SUM -

Introduction

Scenario:

You want to migrate your existing SAP ABAP system to the SAP HANA database

Your SAP release needs to be upgraded prior to migration

Use the database migration option (DMO) of the Software Update Manager (SUM):

it combines SAP upgrade and database migration to SAP HANA in one tool!

Benefits:

Migration steps are simplified

System update, Unicode Conversion, and database migration are combined in one tool

Business downtime is reduced

The source database remains consistent, so a fast fallback is possible

MotivationIf you want to migrate an existing SAP system (running on anyDB) to a SAP HANA database, required steps may be a dual-stack split, aunicode conversion, a database upgrade of anyDB, an upgrade of your SAP software, and a database migration to SAP HANA. TheSoftware Update Manager (SUM) includes an option that combines the upgrade with the database migration "database migration option"(DMO) for SUM. It is sometimes referred to as the one-step migration procedure, compared to the classical migration (i.e. heterogenoussystem copy, using Software Provisioning Manager).The DMO is an inplace-migration (instead of a new installation): it upgrades and migrates the existing system while keeping the system-ID, host name, and connectivity settings stable.

DMO for SAP NetWeaver BW and for SAP Business Suite systems DMO is available with Software Update Manager 1.0 SP09, and can be used for systems based on AS ABAP. It can be used for SAP

NetWeaver BW systems from 7.0 SP17 (and higher) to migrate to 7.31 (and higher). And it can be used for systems part of the SAP

Business Suite 7.0 (and higher) to migrate to a level corresponding to SAP BASIS 7.40 (for example "SAP enhancement package 7 forSAP ERP 6.0").

DMO processing overviewThe processing sequence is based on the shadow system functionality of SUM: the SUM creates the shadow repository on the traditionaldatabase until downtime phase, while in parallel the SAP HANA database is setup (client, schema, ...). Then the shadow repository is

copied to SAP HANA, the database connection of the SAP system is switched to SAP HANA database, and then the downtime starts.After migration of the application data (including data conversion), the upgrade is finalized and the SAP system runs on SAP HANA.

The traditional database continues to run and it is not modified at all, so it remains a fallback throughout the complete process.

DMO is using SAPUI5Althought DMO is based on the "standard" SUM, a new user interface (UI) is used - but only for the DMO procedure. The UI is basedon SAPUI5, so it's running in a browser, and offers some comfortable features like checking the log files without having to log on to the

OS of the application server.The new UI is currently only available for the DMO procedure, but in the long run, it may become available for other use cases as well.

Please note that for a SAP Business Suite system based on SAP NetWeaver 7.40 (i.e. systems part of SAP Business Suite 7

Innovations 2013), your SAP NetWeaver Hubs must be on 7.30 or higher. For details,

Thanks Rubarth, for the details.

I am currently taking first steps in exploring DMO option for migration to SAP HANA and your latest blog is more than a

handful resource.

Thanks much.

Hi Boris,

very nice presentation!

I can use DMO also without HANA as a target? For example, to perform a migration of ERP 6.03 from Windows as s.o. and

Oracle as db, to Linux Suse as s.o. and Oracle, with upgrade to ERP 6.06 in one step?

Thank you

Regards,

Walter

Hi Walter,

indeed this procedure is exclusively for SAP HANA DB as target db only.

Walter CastagnoApr 3, 2014 5:45 PM (in response to Boris Rubarth)

Ok!

The possibility to not change hostname and the SID allow you to use the same application server with

hana, then you not need to buy another server! This is a great solution!

But is it also possible to do a real migration? I mean at the end you have the database in HANA and the

PAS installed in another server that you specify during the procedure.

(then the source system is only stopped, if you start it you can use it)

Thank you

Walter

Hi Walter,

not sure if I understand your scenario ... DMO isa real migration.

System-ID is not changed, host of primary application server is not changed, "only" database

host is changed - and database type, of course :-)

So you do not specify the PAS server during the procedure, but you start the SUM for DMO on

the PAS host.

The source system does not exist after the migration, so it is not the source system that is

stopped, but the source database that is no longer used.

I think the blog on DMO technical background is helpful to check the architecture:

DMO: technical background

Hi Boris,

I checked your post "DMO: technical background".

I'm sorry, my question is not clear, I try to explain.

After the migration to HANA my goal is to have 2 systems:

- the source system of the migration that is unchanged and available for user.

- the target system, that is HANA DB + PAS installed in a new server created for thi

purpose.

I don't know if DMO allow this possibility or I have to use SUM (obviously not in one

step).

Thanks

Walter

5/15

a systemis a combination of a database with one (or several) application

server;

"application server" in the sense of software (instances)

with DMO you will have only one application server, so only one system at

a time:

either the new one or the old

your scenario to have 2 systems afterwards is rather a copy and an update(with migration), not a pure migration; so even with the classical migration,

you will have to do a copy first, and then update one of the systems

Does that fit to your concerns?

Hi Boris,

another scenario:

I want to migrate my SAP system to HANA and migrate also the o.s (eg. from windows to linux). I can use DMO with the

process described in your post to obtain my system WITH DB on HANA and PAS on windows. Can I turn off definitively the

PAS and install a new PAS on linux (new server) on top of HANA DB ?

Thanks

Walter

Hi Walter,

sorry for the delay ... not sure what the overall scenario is. I can only answer concerning DMO: DMO can not "turn

off the PAS and install a new PAS on linux".

HiWalter Castagno,I have the exact same scenario as you had asked Boris Rubarth.I want to migrate my SAP system to HANA and migrate also the OS of PAS/App server (eg. from windows to

linux).

As you have already tested the DMO, can you please let me know whether this is possible with DMO?

If this is possible, will the source system (with PAS on Windows) be usable after migration?

Thanks,

Roshan

Hi Boris,

thank you for your reply! In the mean time, I've tested DMO tool successfully!!

Only one doubt: in a TechEd2013 presentation (ITM212) I saw that DMO support nZDT Maintenance capabilities but during

my test, in "Advanced parameters for the procedure" the tool says that nZDT Maintenance capabilities are not supported for

database migration and then are not used. Im' a little bit confuded :-)

Do you know what is the correct information and, if not supported, in future will be supported nZDT Maintenance with DMO?

Thank you for you help

Walter

Hi Walter,

Unfortunally all nZx technologies available for SUM natively, are not available with the DMO option due to thedatabase migration option procesure itself.

Three things to know when migrating SAP BW on SAP HANA

Hi Walter,

indeed nZDMin SUM is not available for the DMO procedure, that is why you have seen the information on the

screen: something like "nZDM not supported".

Background: the nZDM option is only visible when choosing the preconfiguration mode "Advanced", see

blogSettings to activate downtime minimization capabilities in SUM- but for DMO, the option is not offered, so

when choosing mode Advanced, a text is displayed to explain that nZDM not supported with DMO

Please note that we distinguish between nZDM(near Zero Downtime Maintenance) which is an option for SUM and

nZDT(near Zero Downtime) which is a service offering (seeSCN document).

The slide in ITM212 explained the nZDT approach, which may be combined with DMO, but this does not mean that

"with nZDT, nZDM in SUM is used for DMO".

For DMO, we hope to offer a similar approach like nZDM for SUM in the future - stay tuned.

Best regards, Boris

Hi Rubarth:

In the SAP Presentation "Migration to SAP NetWeaver Business Warehouse on SAP HANA Best Practice Update 2014" I

saw that DMO can be used to:

1) Upgrade BW

2) Migrate BW from Any Database to HANA

3) Move BW on Premise to HANA Enterprise Cloud

in a single step (slide 14 of the file).

For this option the process is move the CI from the On premise data center to the cloud and then run DMO from that instance.

We are interested on that option but I have not been able to see more information on it.

Do you know where I can get more information on this option?, Do you have any comments/suggestions on it?

Thanks

Hi Luis,

for the motivation, you can check the following Document -Overview - SAP HANA and SAP NetWeaver AS

ABAP o... | SAP HANA

to do this, use the SWPM and Install the CI to the HANA applicance, where it may fit.

for Example on a single node create the default file system for your ABAP system and do the memory settings for

HANA to ensure to have enough memory for the Primary Application Server.

depending on your existing OS for your "old" Primary Application Server, you have to choose now Linux X64 as

OS now. You can have mixed CI/DI Installations depending on that.

This is independig either you do this in your on premise, or in the possible cloud Landscape.

used to move BW from on premise to any Cloud provider (basically we are planning to upgrade, migrate

to hana and move from on Premise to IBM cloud (another data center)).

2) For this DMO option, do I need to move to the cloud the instance having message server and enque

server (ASCS) and also install on the cloud a Dialog server, or just installing on the cloud a PAS with

DIA and BTC processes will be enough leaving ASCS on Premise

this is supported in a scale out deployment???

Hello, can anyone tell me if there is a way with the new UI for the DMO of SUM whether I can set up an alert action (e.g.

running a script to send an email) to be triggered when the process has stopped awaiting user input ? This was a very useful

feature available with the old Software Update Manager interface. Thanks.

Hi Greig

I asked the question some time ago to Boris [SUM 1.0 SP11 wasn't yet released at that time], and the answer was no.

So, I ended up setting up a crontab script looking for the file /usr/sap/put_/SUM/abap/tmp/upalert.log, if the

file existed then the script would send an email alert with the contents of the file in the email body,,, This is

obviously not as reactive as the "old" non-DMO SUM but it is a workaround...

Hope this helps.

Kit,

No, you need to SWPM for migrating your Source instance to SAP HANA if its already on the required Netweaver

stack. This will fall under Classical Migration of SAP ABAP systems to SAP HANA.

The software update and migration is integrated process in DMO UI and there is no option to choose either one of

them.

Hope this helps.

mistake, now i have spent lot of time and efforts to bring DMO to preprocessing phase, i looked at all the files to see if i can

edit any config file like Keydb.xml to correct and i am not able to find. Is DMO smart enough to identify and give me an

option to modify/correct my input later point of time ? Please advise

Thanks,

Aravind

Hi,DMO is an integrated part of SUM, so there are no kexdb.xml file(s) at all.

Instead yo have several configuration files, which are described in the DMO Guides

likehttp://scn.sap.com/docs/DOC-

46824orhttps://service.sap.com/~sapidb/011000358700000950402013E/SUM_SP11_DMO_RTC_13.pdf

Boris RubarthSep 1, 2014 1:50 PM (in response to Aravind sap)

Dear Aravind,

the system-ID (SID) of the target SAP HANA database is used for the connection from SAPup to the SAP HANA

database. If you enter a wrong SID, the connection will either not work (and you'll get a connection error), or it will

connect to that database, which seems to be the case in your scenario. So you will have to reset the DMO procedure

to withdraw any changes, and start again, now specifying the correct SID.

Aravind sapSep 1, 2014 5:41 PM (in response to Boris Rubarth)

Dear Boris,

Thanks for the response. I am trying to see if there is any alternative instead of doing a reset of DMO. Can

SAP SID and HANA SID be the same ? I see only license issue will come as we can not have two SID's ,

but system should work.

Is license key during the migration is mandatory ?

Thanks,Aravind

Aravind,

If SAP PAS and HANA are running on different servers, then you can maintain same SIDs. But

if you are looking to install SAP PAS on the same HANA server then you have to maintain

different instances.

Refer to OSS ntoe1953429for moe details on this. Hope this helps.

I understand that, But can you generate two license keys with the

same SID? To my understanding you can not have two SID's in

the landscape, they should be unique and you wont be able to

generate license keys . HANA DB license key request needs

amount of memory.

DMO will ask for license key during the migration, after

migration which license is showed in slicense? i can check this

myself may be in other two days , my migration is in middle.

After migration the SLICENSE will show the

Netweaver license for HDB database. Maintaining

same SIDs is an option but not mandatory, and you can

go with the best practices you are currently following.

so you have to have a brand new HANA database installed in another server?

For a while you will have 2 databases running at same time? Until you deactivate the old MSSQL as on my case?

My problem is that DEV and QAS will still be on MSSQL... mgmt wants only PRD running on HANA. I'm not confident that

it will work out.

Do you have any expertise to share on this scenario?

Hi Julius,

I guess it is generally recommended to have a homogenous landscape. Furthermore, QAS testing cannot be used to

identify / predict potential issues in production if the underlying database is different. And I am not sure what

happens if HANA-optimized objects (e.g. Info-Cubes) are overwritten by change requests originated from a BW

system on a non-HANA database.

We are running the DMO option of SUM to upgrade our BW system to 7.4 and migrate it to HANA DB. We are using SUM

version SP11

We are close to being the downtime portion of the process, but during the initial phase we selected the option to "compare

content of ALL tables (target vs Source DB). We now realized that maybe was not a good selection since this could add too

much time to the process and maybe adding some room for errors there. The database is not too big, it is only 400 GB in the

legacy DB.

Is there a way to change that option to "Do not compare table contents" without resetting the upgrade and repeat from the

beginning? As I said we are close to beginning of downtime, so we do not want to repeat the whole process.

Thanks

Hi ,

Please seePhases behind DMO R3load parallel export/import during UPTIME and DOWNTIME to target HANA

DB

That explains uptime and downtime phases which includes table count. as far as i know there is no option in DMO to

change the table compare option, you can only change number of parallel process during the DMO runtime.

DearBoris Rubarth

I have come across a situation where DMO hangs when i click on any of the upcoming phases . I was trying to see how many

current steps remaining in current phase and by mistake when i clicked on one the steps which din't finish , DMO activated

check mark until that phase and stops there. I had to restart DMO and continue from the last phase.

Normally we can click on phases and scroll down in SWPM, but in DMO case it is not working.

Is it normal , Please advise

Boris RubarthSep 15, 2014 9:49 AM (in response to Ravindranath Gangampalli)

Dear GR,

where is that phase list (you have clicked into) located in the UI?

The phase list on the right hand side shows the phases of the current roadmap step, and a click on a phase name will

open the respective log, if existing. But the DMO run will then not stop at this phase.

The Utilities / breakpoint menu shows the phaselist as well (for all roadmap steps). Marking the checkbox for a

phase creates a breakpoint. When the phase is reached you can simply continue the procedure, using the continue

option on the UI.

Dear Boris,

Thanks for responding.

Yes, I am talking about the phase list which is located in right hand side of the UI. I did not set any break

points during the migration. It happened to me two times during the migration, when ever i clicked on one

of the phases in phase list (which is not yet finished) DMO puts a check mark on all the phases till the one

phase that i clicked and it stops there. Once i reboot DMO i can continue from the Original phase it was

running.

Dear GR,

our guess is that the click in the phase list could have stopped the automatic refresh of the UI

(not the run itself), and a manual browser refresh (F5) may have solved the issue.
