2003 SBS to 2008 R2 Standard seperate servers

kseath used Ask the Experts™
I have read over alot of migration white papers and have a few questions on some of the details.  Background:  I have a client with 75 users on an SBS 2003 box.  90% are POP accounts on exchange.  The way I see it I have two choices:  Start all over and create a new domain and do profile changes and domain switch etc to the office (10%) and just recreate all the user accounts and passwords for the POP users (90%) or migrate the Active Directory and domain etc from SBS.  pros and cons anyone?  I hate moving profiles and synced folders on laptops etc to a new domain not to mention recreating 75 user accounts.  My fear is that in moving over the AD it will still have the 75 user limitation or other SBS related limits.  anyone put these fears to reat or have done a similar migration?

Should also mention that I plan to split AD and file print services to one box and Exchange 2010 on a second 2008 R2 box.
We have migrated clients from SBS 2003 to Windows Server 2008 R2 running Exchange 2010 perfectly fine. You won't find yourself imposed by the 75 user limit once you're on the new platform.

Please see the following link by a fellow EE Expert for a simplified and guided run through: http://demazter.wordpress.com/2010/04/29/migrate-small-business-server-2003-to-exchange-2010-and-windows-2008-r2/

Just make sure all your Outlook clients are 2003 and above to ensure you don't have any problems connecting to the new Exchange server.

Best of luck!

A final recommendation, do not move the FSMO roles from SBS 2003 to Server 2008 R2 till you really need to, as you will effectively start the count down timer from 7 days.

You can perform an update to extend this to 21 days too: http://support.microsoft.com/default.aspx?scid=kb;EN-US;943494

Moving to standard edition will remove the limits imposed by SBS.  It's the exact reason people do it.

My guide has already been posted above.

I'd certainly be migrating 75 users.  The work involved in rebuilding is just way too much.  Not to mention the downtime which wouldn't happen with a migration.


Good comment.  thanks for the resassurance. I have had issues in the past where client PCs are still looking for the old server to sync offline files with.  once that server is gone I could never seem to keep them from trying to sync.
