I am upgrading to a new SBS 2011 server and I am having to do a clean installation because the current source domain was configure as a single label domain. I am using this blog to assist me http://blogs.technet.com/b/sbs/archive/2009/05/01/sbs-2003-to-sbs-2008-migration-to-a-different-domain-name.aspx but this refers to SBS 2008 and Exchange 2008.

What is the procedure for migrating the email from the Exchange 2003 server to the Exchange 2010 server.

Maybe I am missing something but I am not installing Exchange 2010 into an existing 2003 organisation, I have a completely seperate domain and I want to move to email from an SBS 2003 with exchange 2003 server to an SBS 2011 with Exchange 2010 server, there is no link between the 2 organisations as this is SBS running on 2 seperate domains.

I was hoping for some help using ExMerge or a similar tool to help me export and import the email but i havent done this for Exchange 2010 before.

You can use exmerge on your 2003 system to export your mailboxes to PSTs, then use the powershell cmdlets to import on the new system.

http://blogs.technet.com/b/sbs/archive/2011/05/09/how-to-import-and-export-mailboxes-using-pst-files-in-sbs-2011-standard.aspx

Exmerge has a limit of 2GB though so if your mailboxes are larger than 2GB you'll need to use outlook to export to PST.

Do you know if this will work if the source domain is a Single Label domain I am getting authentication errors regarding the source domain.

This method doesnt work as you need a 2 way trust and trusts are not possible in SBS thanks for your response though does anyone have an idea on how to do this or am I stuck using PSTs

If you have PSTs, you should be able to import them in to the new user's mailbox by using the New-MailboxImportRequest  cmdlet in exchange management console on the new server.

Also as far as AD is concerned, if you want to migrate anything from the existing AD you need to install SBS in migration mode, as you mentioned there are no trusts possible so you'll essentially be setting up a new active directory entirely from scratch.

once you set up the new users they will have blank mailboxes, you can import PSTs using the New-MailboxImportRequest cmdlet.

just figured i'd pass along to go in to WSUS and approve all the updates first.
there is a bug with exchange 2010 SP1 where importing PSTs does not work until you install at least update rollup 3 (the current rollup is 5)

thanks for your reply but migration mode is not possible because the source domain is an SLD.

I am just going to use PSTs and import them thanks for the input.
