It’s might not be surprising that TFS 2017 upgrade has changes
at the process like elastic search installation as part of TFS search
infrastructure.
But you may be surprised by the NEW ability to
prepare a staging environment for the upgrade. Which means: You can restore the
production databases to a new environment and the upgrade will fix and adjust
the restored tables to the new machine (instead of manual steps of remap DB)
All steps shown below…
Enjoy!
