About Pax Migration Experiences

ARQUITECTURES

COEXISTENCE x MIGRATION

Mail Migration

• One time process

• Easier than coexistence

• High risk

Mail Coexistence

• Gradual process

• Require more efforts

• Low risk

• Most users prefer this option

EXCHANGE TO OCS

• Not easy to use and manage

• Only migration tools, don't provide coexistence solution

• Development needed (VBScript) to create alias on Exchange

EXCHANGE TO OCSESMigration + ExMigration

• Third-party tool, cost about U$ 6.00 to U$ 9.00/user

• Unique tool for loading users, migration calendar, contacts and mail

• Graphical interface, easy to use

• Coexistence support (automatic create alias and set forward)

• Support standardization for mails and user names

• Sold to Quest in 2005, now support just migration from Notes and

Groupware to Exchange

• Desktop migration tool

OCS 9i to OCS 10g - Overview

Probably the first partner doing it

• Note “How To perform a Plain IMAP2IMAP Migration With Esmigration”

(Metalink 398478.1) by 2007, we did in 2005

What Functionality is Lost?

• The ability to respond to the meeting (accept, tentative, or decline)

• Free or busy information for both you and the organizers

OCS TO OCS

OCS 9i to OCS 10g - Steps

Pre Migration (shell script)

•Change user password at new system and keep original password (Trick 1)

•Set forward at old system to alias that point to new system

Migration (ESMigration Tool)

•Use ESMigration to do a IMAP to IMAP copy of messages

Post Migration (shell script)

•Restore user password at new system (Trick 1)

•Migrate Calendar (Meeting and Notes) entries via uniical (Trick 2)

•Migrate Tasks via unicpinu/unicpoutu (Trick 2)

•Migrate contacts using migrate_emailaddressbook.pl (Trick 3)

OCS 9i to OCS 10g – Trick 1

Change the user password to migrate and back the original one

$ORACLE_HOME/bin/ldapsearch -D cn=orcladmin -b "cn=plugin,cn=subconfigsubentry”

objectclass=* orclpluginentryproperties

cn=adwhenbind,cn=plugin,cn=subconfigsubentry

orclpluginentryproperties=(!(&(orclisenabled=ENABLED)(objectclass=orcladuser)))

cn=adwhencompare,cn=plugin,cn=subconfigsubentry

orclpluginentryproperties=(!(&(orclisenabled=ENABLED)(objectclass=orcladuser)))

$ORACLE_HOME/bin/ldapsearch -D cn=orcladmin -b "dc=br" cn=rodrigo orclisenabled

cn=rodrigo,cn=users,dc=domain,dc=com,dc=br

orclisenabled=ENABLED

OCS 9i to OCS 10g – Trick 2

Moving Calendar with uniical and Tasks with unicpinu/unicpoutu

OCS 9i to OCS 10g – Trick 3Exporting contacts via LDAP, converting and importing again

To convert contacts we used the upgrade tool migrate_emailaddressbook.pl:
