Hi Folks,
I need clarification on my migration steps.
I desire to migrate and split into two servers
I have a single 2003 server with exchnage 2003 installed, this is the only DC and server currently in domain.
1 server will be the new DC with AD and hold all user profiles and Documents
2 The second server will become the new exchange 2010 server

I plan to configure the 1 server as a member server or secondary DC
2 move all the user profiles and home folders to this new DC server 2008 R2
3 Build second server and install exchange 2010 and migrate mailboxes to here
4 once exchange 2010 is up and running and all mail acoounts migrated and on here
5 Then promote the new DC as the primary domain server
6 Then demote old 2003 AD server 2003
7 Confirm users and profiles are all functioning from the new DC
8 Remove old exchange 2003 from old server 2003
9 decommision old server 2003 and remove from domain and shut down

How does my steps appear to you is there any gotchas I might look for??

your plan is good.

I hope the migration of  mailboxes from exchange server and exchange 2010 running.. includes the migration of public folders, configuring and send and receive connectors to point to exchange 2010, OWA url point to exchange 2010 etc..

I might suggest to complete the DC part first and then do the Exchange transition part. I guess you know during this process you need extend the schema etc. Make sure to have full backup of current servers before you do the decom. Not sure how big your env is, lot of time application servers are tied to old server and after decom only you find it.

You also need to remember the certificate requirement for Exchange 2010 and Client requirement too...If you have using Outlook 2003 you might need to install a patch on all clients else you will find connection, free/busy, shared calendar or mailbox access issues.

Also if your user configured any shared mailbox, ask them to note down before you move the accounts to 2010 Exchange servers, because after move, it might be gone.

Next, if you are using Public folder, you need to do PF migration first and then mailbox migration. Remember, there is a known invalid character issue with PF migration. If current, PF have any invalid characters like trailing space etc, in that case that won't replicate and you might need to fix that before adding the replica.

I don't want to scare with this long story, however i did a migration recently and it took me a year as customer setup was huge and spread across the globe.

Hope you find this useful. Rest other EE's already agreed with your plan.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Go to disagree about the plan being good.

"I have a single 2003 server with exchnage 2003 installed, this is the only DC and server currently in domain."

"6 Then demote old 2003 AD server 2003
7 Confirm users and profiles are all functioning from the new DC
8 Remove old exchange 2003 from old server 2003"

That isn't going to work. Running DCPROMO on a server with Exchange installed will break Exchange and you will be unable to remove Exchange 2003 correctly.

Remove Exchange from the DC first, then restart both servers. Only remove the GC role from the old DC once Exchange has been removed. While Exchange is installed on the server all Exchange servers (the new one as well) will ONLY use that DC. Therefore by removing Exchange and then rebooting both servers will ensure that the new server will use the other DC.

Simon.

Don't know how much of a guru you are with Exchange 2010, but MS did not make this a simple and easy migration.  I am including documents that MS provided for me that made the process go so much more smoothly.

I agree with jhyiesla, migration is not that simple. Lot of things you need to figure out and fix them during the actual migration.
