Migrating SBS 2003 to SBS 2008 ?? Best practices and HOWTOs ???

Hi Experts,

I have a network running SBS 2003 and I just installed SBS 2008 in a separate box. My new SBS 2008 deployment is in a separate network segment.

What will be easiest and reliable migration between SBS 2003 and SBS 2008. Any useful howtos and resource for this ?

Please advise & thanks alot !

The above guide is all you need unless you run in to issues.

From my experiences you need to ensure the health of the 2003 server is good, if it has issues the migration will be a headache, review your event logs, run best practices analysers on it, run dcdiag, and netdiag and ensure no errors pop up before the migration. Otherwise that guid is easy to follow and comprehensive.

Thanks Dinga: some quick question can I do this in a same network segment ? Until I migrate all the data and configurations and after that I need to change the IP segment. And old external IPs should NAT to the new SBS 2008 server. (that's controlled by the PIX)
I would turn off the DHCP in the PIX, and have the old server do it, then join the new server as per the document above, the only reason being the PIX wont have the SRV records for the domain controller. After the migration if you really must use the pix, turn DHCP off on the new server and turn the PIX back on.

You probobally could run it up on a seperate network, but it seems like the long way of doing things, you would need to move mailboxes over manually, set up all your accounts, move files over manually, etc.
