i saw posts on intra-forest mailbox moves already, i was wasn't sure
if that i what i needed. the ADMT book does not talk much about the
exchange part. i was hoping that it would treat exchange just like any
other member server,,,, wishful thinking i guess



This is a complex process to list out. I just did one two months ago for a
150 user system. There is some preparation establishing trusts, the ADMT
process, SIDHistory to insure coexistence and they can use their old
profiles with their new user account, then cross-forest Exchange
permissions, then moving mailboxes. And that move mailbox tool, however nice
it is, is complex and took some testing with test accounts and tweaking
permissions, before getting it to work right.

Then we PST'd the PFs, etc.

sounds like it is exactly what i need to do.. do you have notes/web
links, list of gotchas?


Thanks Paul

Hi Paul,

I don't have a specific step by step procedure compiled at this time. I have numerous notes on it but they are in various notepad docs, emails, etc, and they are not compiled into one specific doc. I usually do put together step by step docs such as this, to help folks in the newsgroups, but I haven't yet with this procedure because besides being scattered and the procedure having many facets, my notes are customer specific with domain names, user accounts, passwords, etc, that it will take me some time to go through to compile it into one doc, and I do apologize I am short on time to do anything with this at this point. I am assisting with a startup company at this point that is consuming most of my time. It's one of the things I've been planning to do, but I just haven't got around to it.

Also, I believe you have a misconception about ADMT. ADMT is SOLEY to migrate user accounts, group accounts, and computer accounts, with numerous other features such as security translation for accounts and using the SIDHistory option to allow new accounts in the new domain to access resources in the old domain, among other things. It has NOTHING to do with Exchange. You migrate the accounts first, because the user account must exist first, then you perform an interforest mailbox move to the newly created user account.

My suggestion is to read up and study ADMT to understand how it works and what it does. I also suggest to migrate a test user account that is mailbox enabled and see how it works for you. If it works for the one, it will work for all of them.

Say for example, if you successfully migrated a user account, but having difficulty with the movemailbox portion and have gone through as much as you can do to get it to work, you can call Microsoft PSS and they will be glad to assist you with a step by step and pretty much do it for you for the one charge.

Here are some notes on ADMT and Exchange migration, but nothing specific as to a step by step.

If Exchange is involved:

If Exchange 2003 is involved, you can use the Exmerge tool.

If Exchange 2007 is involved, you would need to use the MoveMailbox method from the source org to the target org after migrating user accounts.

This is a weak overview of the mailbox move:
