Replacing SBS2003 with Server 2008 & Exhange Standard 2010

this isn't to different form migrating to an actual SBS.  You want to make sure public folder have replicated to the new Exchange server, and you want to make sure you properly remove the Exchange 2003 portion.  Check out this series of articles for help.

At the end, there's also a link to a MS Tech article about removing the last Exchange 2003 server form the domain.

You will need disc 2 from the SBS install set to remove Exchange 2003 form the SBS.  If you haven't already, promote the new server to a DC and Transfer the FSMO roles.  ten you have 21 days to demote the SBS server (7 without a patch but you should be mostly finished by now anyway.

new have the old hardware server a new role you MUST remove the SBS OS.  It will not function if it's not the PDC. (7 day limit I talked about earlier)

If you use Demazter's step-by-step walk through, you won't go wrong:

Uninstalling Exchange on 2003.. will that automatically remove the "dependencies" that my 2008/exch2010 server is currently having with the 2003sbs server? Right now the exchange domain is "connected" to the sbs2003 exch... or are there OTHER steps?

I'm asking a question... linking me articles that are 8 pages long where 20% of the info is info I need isn't helping me much...

Thanks

What you are doing is a process that is long and can be complicated.  If you are doing this without following a guide, then the chances are it will go wrong.  If you follow a guide, then the chances are it will work happily and you will complete the migration happily.

If you have a read of Demazter's guide - have you performed all the right steps in the right order?  If you haven't, then I suggest you slow down and make sure you have, if it isn't too late.

Have you moved Public Folders across?

Are all mailboxes moved?

Is the Exchange 2010 server now managing the GAL updates?

Have you installed an SSL certificate (SAN / UCC)?

Have you installed the office filter pack?

Did you remove the Recipient Policies from the Exchange 2003 server?

Have you removed the Recipient Update Services?

Have you removed the Routing Group Connector?

All this is covered in the guide and needs to be performed if you want things to go well.

Yeah I moved one mailbox over to the new Exchange  2010. It can send out email fine. Not recieving email on the Outlook 2010 client that has the mailbox on the new 2010 server however. Keep getting:

"Task: 'person@domain.com' reported error (0x8004010F): 'The operation failed. An object cannot be found'

Goggling this I get articles regarding needing to rebuild the Offline Address List. Trying that gives me additional errors:

Ran the Best Practice Analyzer. Realized I have lots of issues where it feels the domain prep wasn't exactly successful enough. The new Exchange Server is complaining about the old server "Current Domain Prep Signature is 12639" which is unknown..

Gonna do a setup /domainprep shortly once I get the exch2010 dvd in the drive...

Yes I already added that autodiscover record last night... and have been reading the guide..

Thanks

So I just ran a:

 setup /PrepareLegacyExchangePermissions

using the Exchange 2010 DVD's setup.exe.. now I ran the BestPractices tool and all those errors were gone...

Spoke too soon.. nevermind they're not
