Between our Sandbox and Production instances of your TeamDynamix environment, they do not copy up from Sandbox to Prod. If you made changes and work in Sandbox and like to have that in Production, you would have to manually re-create it in Production. We only copy down from Production to Sandbox environments respectively. If you are non Private Cloud, this is done on a quarterly basis. For more information on our instances and refreshes, please check out this KB: https://solutions.teamdynamix.com/TDClient/1965/Portal/KB/ArticleDet?ID= 6357
I know I heard discussion of at least something, possibly services, being able to be copied from sandbox to production in the TDX Converge conference in June 2021 recently, but I am not finding the release notes mentioning which particular functionality it applies to.
