I forgot to add: Prepare-MoveRequest will create a new mail enabled Exchange object on the destination domain that will point back to the source domain, and will include all of the X500 and SMTP addresses, so you will not need to manually export and import these from the source domain, i.e. mail flow will continue to work as expected.
And once Remote-MoveMailbox is run, it will automatically convert the mail enabled object on the destination domain to a user mailbox. And, it will convert the user mailbox on the source domain to a mail enabled user object on the source domain, and will forward all email to the destination domain. So, users from the source domain will still be able to log into their computers, but they will no longer have a mailbox on the source domain. -Aakash Shah From: [email protected] [mailto:[email protected]] On Behalf Of Aakash Shah Sent: Monday, February 24, 2014 5:09 PM To: [email protected] Subject: [NTSysADM] RE: ADMT & Exchange I don't have any documentation online, but here is an overview (I am using the built in Exchange cmdlets, so there may be someone else that has documented this online): 1. Exchange Migration a. A few days before actual migration: i. Run Exchange Prepare-MoveRequest cmdlets on ALL production mailboxes (if you don't do all, users will have issues sending to users who were not included in this "prep"). ii. Use ADMT to sync their passwords (we are not migrating a lot of their older settings and hence don't need to sync any other attributes - this will differ from your scenario). b. Production night(s) i. Run Exchange Remote-MoveMailbox cmdlet on the mailboxes that are being moved that evening. c. Client Side i. Remove old Outlook profile, add new Outlook profile to point to new server. Do you attempt to reconfigure the server settings in the existing Outlook profiles. From what I recall when we first did this about 2 years ago, it caused both client side and server issues (client side mailbox kept "flickering" and showing and deleting folders, and server logs ballooned - not sure what exactly was the problem, but we stopped attempting to reconfigure the existing profile and haven't had any problems since). 2. AD Migration a. Resources will be migrated to new domain. b. When the users get their new Win7 computers, they will be logging into new domain and will have access to their old resources. The Exchange migration part we have done since we've been doing that for some time now successfully (both Exchange 2003 and Exchange 2007 sources). The AD migration part is something we are still formulating now - our task has been to vacate the existing Exchange servers in each forest first, and then work on the rest of the AD migration part next. There are likely other ways to approach this too, but this is the approach that we happen to be using. -Aakash Shah From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Ken Cornetet Sent: Monday, February 24, 2014 5:27 AM To: [email protected]<mailto:[email protected]> Subject: [NTSysADM] RE: ADMT & Exchange Can you provide pointers to the documentation you are using to do this?

We are doing something similar now with a Win7 upgrade project. We are moving their mailboxes first (we're currently in this phase), and will then be setting up the users on the new forest with their Win7 computers after we've migrated their file server resources over. -Aakash Shah From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Ken Cornetet Sent: Friday, February 21, 2014 11:15 AM To: [email protected]<mailto:[email protected]> Subject: [NTSysADM] ADMT & Exchange I'd think this would be a common question, but my google-fu has failed me. Here's my situation: Given a forest with users with Exchange mailboxes, I need to migrate the users to a new forest and move their mailboxes to new Exchange servers in the new forest. My question is: Is there any way to NOT do both migrations at the same time? In other words, can I move their mailboxes the weekend before I do the user migration? Or vice-versa - move the mailboxes the weekend after the migration? All of the documentation I can find on using ADMT to migrate exchange enabled users talks about moving mailboxes coincident with moving the user. As part of a company spin-off, I have several locations with hundreds of users each where I need to migrate users to a new forest. I doubt I'll be able to get more than a weekend at each location to complete the user migration, so I'd prefer to do the mailbox migration done either before or after the user migration. I understand there will be GAL sync issues to address - I can handle that.
