Why Change Corporate Mail Platforms?

It really doesn’t matter any more…once you’ve been told to do it!

Migration Means...?

Moving Users Moving Documents


Migrate or Cut-over?

Imperatives– No disruption to your business– Continued delivery of ALL mail

Cut-over may be cheaper– Supporting single infrastructure

BUT can you afford the risk?– Can everybody use it?– Will ALL the mail still get through?


Before You Start

Have NT/Exchange Infrastructure in place and tested

Have your Help Desk people trained in:– Use of Exchange– Administration of Exchange– Your migration process

Have Exchange and ALL-IN-1 talking to each other


Why Run Both Mail Systems in Parallel?

Continued Delivery of ALL mail during the transition

Allows for staggered user training and migration

Breathing Space during any teething problems


All Staff Must Be Addressable from Both

Platforms Mail directories must be synchronized and

kept up to date Distribution lists must be synchronized and

kept up to date Auto Forwarding in place:

– From ALL-IN-1 to Exchange (Exchange users)– From Exchange to ALL-IN-1 (ALL-IN-1 users)


What About…

VMSmail?– Auto Forward to Exchange

“SUBSCRIBERS:” Mail?– Only for ALL-IN-1 users– Use real distribution lists


User/Help Desk Perspective

User requests migration Help Desk enter user’s ALL-IN-1 and NT

Domain usernames into ALL-IN-1 screen Next morning

– All user’s mail is delivered to Exchange– User’s Exchange address appears in all mail

directories and distribution lists– No more mail is delivered to ALL-IN-1


ALL-IN-1 Customization

1 FMS Entry Form and FDL– Used to enter Usernames into file as input for

overnight processing 2 DO Scripts

– Migrate Users Part 1 (each night)– Migrate Users Part 2 (each morning)


Migrate Users Part 1

– ALL-IN-1 Auto Forward to Exchange– Profile MNODE = “N”– NETWORK.DAT Deleted = “Y”– New entry in special NETWORK.DAT on MR

Hub– VMSmail Auto Forward to Exchange


Migrate Users Part 2

– Check for user’s Exchange address in ALL-IN-1 system distribution lists

– Profile RCV$SUB = “N”
