We recently upgraded from CM 2012 SP1 CU4 to 2012 R2 RTM.
During the upgrade, the primary upgraded without issue.
When it came to upgrading our two secondaries(MPs), they both failed.
Had to delete the DB and registry keys and retry on both of them.
Got them both back up and replicating properly and clients reporting in.
Only issue is, all of the DPs hanging off of one of the secondaries have had a massive content redistribution triggered.
It appears as if roughly 140 applications/packages per DP have been triggered for redistribution out of nowhere.
It doesn't seem to have affected the other secondary site.
We currently have over 14,099 packages pending redistribution after the upgrade. Most of which were successfully distributed pre-upgrade.
I can't seem to find any cause for this massive content redistribution in my research.
Any thoughts on what caused it and if there is a way to stop it seeing as the content should already be there?
