I would like to do exactly what is being proposed in this question, but instead of VSTS, I'd like to do it in on a On-Premise TFS(2018):
I've followed the instructions explained here to export and modify my custom project template. However when I follow the instructions here(Step 5 of the original instructions) I get stuck at the "Configure Features" step, that does not appear in my implementation of TFS (Yes, my user account is part of "Project Collection Administrators"):
I'm sort of confused, there are people that claim this can't be done. In fact it's even stated in the process page:
"Changes you make to a process template will only apply to new team projects. They will not affect existing team projects."
But the instructions clearly indicate that it can be, I just done see the "Configure features" link? The instructions indicate that the use case is after a TFS update, but if I just changed my custom template, how would I enable this, so I can implement my changes in the custom template?
