Symptom

tf30045

Root Cause

TF30045 is a generic error message. So this is just one of the possible reasons. I restored databases from TFS 2015.2 to TFS 2015.1 so the App tier is not recognize the configuration database.

Solution

  1. Upgrade the App tier to match the data tier. In my case, from Update 1 to Update 2
  2. Remap the databases (RemapDBs)
  • The upgrade wizard won’t work because it’s already the same version
  • I have to use /Continue when remap the database and don’t have a sound SSAS setup in my lab for TF400673
  • After remap, run the wizard again to finish the upgrade
