Using TFS Azure Devops, there is a repo with valid code being maintained in a secondary branch. However, the master branch is multiple years out of date.
I want to obliterate the contents of master and overwrite it with the contents of the secondary branch.
I understand that mishandling this can cause serious namespaces issues and I would like to avoid that.
What method would you recommend for completely replacing master with a secondary branch in TFS Azure Devops?
