Upgrade process when multiple application tiers RRS feed

  • Question

  • Hello.

    TFS upgrade manual does not tells how to correctly perform upgrade - if we have more than 1 application tier.

    Let's say - we have 2 application tiers (tier A and tier B), they are load balanced.

    When upgrading to next TFS version (on the same hardware) - initially tier A and tier B are running (DB backups have been made).

    Question is - should tier B be stopped (with TFSServiceControl quiesce) - while on tier A installation and upgrade is in progress - or tier B can remain running ?

    This question is due to scenario - while tier A has ongoing installation and upgrade process - users might connect to tier B, and also on tier B - some TFS jobs might run, while upgrade from tier A is in progress.

  • Hi B.Marex, 

    Thanks for your post.

    Yes, as far as I know you should shut down(execute TFSServiceControl quiesce) the Tier B before upgrade your Tier A.

  • Hi.

    Thanks for your reply.

    Everything is clear, I also think that in described case - application tier B should be stopped, while upgrade running on application tier A.

    Thank you.
