I am in the process of migrating the engine to a new cluster. I hope I will accomplish it this weekend. Fingers crossed. What you need to know: The migration is really a backup and restore process. 1. You create a backup of the engine. 2. Place the cluster into global maintenance and shutdown the engine. 3.
