Question

How do I get back TFS(2010) data after I uninstalled it by mistake?

I have SQL Server backups for TFS_Configuration, TFS_Warehouse, TFS_ProjectName1 and TFS_Analysis databases.

I installed a new TFS and now I have new TFS_Configuration, TFS_Warehouse, TFS_NewProjectName and TFS_Analysis databases but I want back the old data from previous TFS.

I try to follow the steps from
http://msdn.microsoft.com/en-us/library/ms404869%28v=vs.100%29.aspx
but now I’m stuck trying to restore the databases from backups (I get verification errors before restore start, that said the databases are different). What should I do?

The main goal is to recover the content files of the old TFS. What options do I have?
Is it possible to programmatically read (to a local folder) the old TFS data?(Which table should I read? In this way I recovered the documents stored in WSS_Content)

Please help! We don’t have any data to work with.

Here are the steps I followed and the problems that I encountered:

• I used “Restore Data to the Same Location” http://msdn.microsoft.com/en-us/library/ms252458.aspx
• After I uninstalled TFS I backed up and removed all TFS databases
  from SQL Server: TFS_Configuration, TFS_Warehouse,
  TFS_ProjectCollection, ReportServer, ReportServerTemp. (I didnt do a
  backup but I deleted TFS_Analisys from SQL Server Analysis instance)
• I uninstalled SharePoint and then I tried to install it back but I
  failed. The solution was to remove WSS_Content from SQL Server, then
  the install succeeded.
• I installed a fresh TFS (without creating the TFS_ProjectCollection)
• Errors at Reporting Services occurred.(because I deleted
  ReportServer, ReportServerTemp). were solved using Reporting
  Services Configuration:Open Database tab ->ChangeDatabase->Create new
  Report server database …continue with default options.
• I restored the ReportServer, ReportServerTemp from backups.
• After TFS install, I stopped TFS Services: TFSServiceControl quiesce,
  then I restored in SQL Server the TFS databases from backups (with
  OVERWRITE option)
• I rebuilt only analisys service:

TFSConfig RebuildWarehouse /analysisServices Update All Service
Accounts TfsConfig Accounts /add /AccountType:ApplicationTier
/account:YourTFSServicesAccount /password:YourTFSServicesPassword
/SQLInstance:YourSqlServer /DatabaseName:TFS_Configuration

TfsConfig Accounts /add /AccountType:ReportingDataSource /account:YourTFSServicesAccount
/password:YourTFSServicesPassword /SQLInstance:YourSqlServer /DatabaseName:TFS_Configuration

• Clear the Data Cache on Servers

• Register Tfs_Configuration

  TFSConfig registerDB /SQLInstance:YourSqlServer /DatabaseName:Tfs_Configuration
  TFSServiceControl unquiesce

• From SQL ServerConfiguration Manager: start services you need
  (Analysis Services)

• From Services start SQL Reporting Services
