Attempted to upgrade 7.9.7 to 7.9.9 on two servers today, one successful, the other I had to roll back to 7.9.7.
After upgrade, neither would start and I ended up having to restore a gateway backup via the GCU to get the first to work. The second, no matter how I went about restoring the gateway would never start up. At best, I could get the web service to start, but the gateway would say faulted.
Ended up rolling back to 7.9.7 to get our services back online.
Anyone have any experience with this or any idea as to what would cause it?
