There has been some progress, regression, and progress again on the git server side of things. On Friday the git service was switched over to the new server around noon. Initial tests were good. Then about 5pm I saw the first problem reports. Permission denied pushing commits. To recover git was switched back to the old server while debugging the problem.
The problem was that I had tested before the database migration and the database migration broke the nfs server groups. That has been fixed. I am once again switching git onto the new server. I might as well mention here that the database has been migrated from the old internal to the new internal0 VM. That movement went very well and was a low stress move. I think I will go so far as to say that it was completely invisible to users. This resulted in git users seeing permission denied errors when trying to push commits. Sorry. Fixed now. Moving forward again. Bob
