I tried recovery whole TFS from backup - just to imitate disaster recovery situation. I backup DBs and then configured TFS with wizard (based on restored Tfs_Configuration database).
But now when I connect to TFS Console and check Reporting I got error:
TF246017: Team Foundation server could not connect to the database.
Verify thath the server that is hosting the database is operational and that network
problems are not blocking communication with the server.
When I click OK I get that everything under Reporting is 'Unknown' and there is no Edit button.

I noticed also that under Application Tier > Reporting Service Summary > Manager URL and Server URL still points to the old server.
Question: How I can configure Reporting for the new server?
