Move Team Foundation Server from One Hardware Configuration to Another with different Servername

Question

Hi,

I move a TFS 2010 from one Hareware to another Hardware (with different Servername). OS: Win2008 R2

Everything works fine (at least I think), except the Reporting Services: In the TFS admin Console I am able to change Url, Warehouse database, Analysis Database but NOT Reportserver. There are still the old URL: Reportserver: http://oldserver/Reportserver, http://oldserver/Reports.

Whenever I try to update the Reports, I get an errormessage eg. "the user or group name 'oldserver\adminname' is not recognized, or cannot add oldserver\adminname to the execrole....

In the commandline: I get the message: "not updating Reporting Services content manager role since reporting services is remote. You need to manually update that role." "Node Warning (ADDRSCONTENTROLE): AddAccountToRSContentRole".

Any Idea to help me solving my problem? Any help would be highly appreciated.
