Error after restoring TFS database to new hardware

Question

I am using TFS 2012. I wanted to test how i can recover from server failure or any hardware failure, So i wanted to shift TFS to new PC.

I followed some articles to restore it. what i did is

1)I had full backup of TFS_configuration and all other collection database.(backup taken using TFSbackup.exe)

2)In new PC i installed all the softwares(such as TFS 2012, sql server etc).

3)created all the windows user account as in old server.

4)When I checked the New PC it had default collection created which was mapped to sql server which i installed.

5)Now i deleted that default collection and restored all databases of my old TFS server(TFS_configuration and all other collection database.)(backup restored using TFSrestore.exe)

6)Now when i checked TFS administrative console it had all the collections as my old server.

7) But when i click on Administrative security, group membership etc I get error like

TF30046: The instance information does not match. Team Foundation expected 368f7830-1c67-4c4c-8bc4-ba3d5b5a5543 which was not found. Please contact your Team Foundation Server administrator.

In this link it was mentioned to change service host id in table. But it didn't work for me.

So please help

Answer 1

You mistakenly configured TFS (in fact it created a default collection). If read carefully Move Team Foundation Server from one hardware configuration to another, you have to run the AT-only Configuration Wizard after restoring the databases.
