Migration from SBS 2011 to 2012R2 & Exchange 2013 setup failing

Dear Experts,

We are in the middle of testing a migration of an SBS 2011 (running Exchange 2010) over to Server 2012 R2 with Exchange 2013 installed. Trying to install Exchange 2013 on our new 2012 R2 (setup as a replica server in the existing SBS domain) but it always fails with an error:

One or more servers in the existing organization are running Exchange 2000 Server or Exchange Server 2003. Installation cant proceed until all Exchange 2000 or Exchange 2003 servers are removed.

We definitely dont have any 2000 or 2003 Exchange Servers in our environment. Pre-Requisites Software has been installed. The exisiting SBS 2011 already undergone a swing migration from SBS 2003 could this be the problem? This migration went flawless and we followed official Microsoft documentation.

Thanks for your advise/help.

Yes, the old SBS is being shown up. How can we remove this using adsiedit without affecting mailflow etc.

Under "Configuration, CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=Domain, CN=Administrative Groups" I see 2 Groups (that of my old SBS 2003 - Servername can be seen und CN=Servers - and that of my new SBS 2011). Should I delete the old Administrative Group or simply the Servername under CN=Servers?

Thanks
