TFS Upgrade – Short Lead Checklist

Any upgrade of TFS, regardless of how basic or complex, whether in-place or including hardware migration, needs to be planned.  That planning should start long before the migration happens and should include all parties of the TFS ecosystem, meaning all the user roles as well as infrastructure roles.

Week or two prior to upgrade



1 - TfsPreUpgrade Tool
꙱ - Done

If your database is large enough to warrant running the TfsPreUpgrade tool prior to the upgrade it can be done while still using the server in production.  The process is non-destructive, cancelable and can be undone.  Given that though it shouldn't be taken lightly or run too far in advance because it does have a performance impact on the server once it's run.

Weekend of upgrade



1 – Backup
꙱ - Done

Backup current TFS data using Scheduled Backups (available since TFS 2012 Update 2).

2 - Backup encryption key
꙱ - Done

Reporting Services uses an encryption key to secure sensitive data that is stored in the report server database. To ensure that you have continued access to encrypted data, it’s important that you create a backup of the encryption key in case you need to restore it later due to changes in the service account or as part of a planned migration.

  • Single-server deployment
    • Backup the encryption key for SQL Server Reporting Services using the Reporting Services Configuration tool or the RSKEYMGMT command-line tool, provided by SQL Server.
  • Multi-server deployment
    • You must backup the encryption key using the RSKEYMGMT command-line tool.

Refer to rskeymgmt Utility (SSRS) for more information.

3 - Uninstall TFS
꙱ - Done

  • Uninstall should only be needed if coming from TFS 2010.
  • Uninstalling TFS does not alter the databases.
