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. Then you create a new engine on the other cluster and before engine-setup you restore
the engine backup.
4. Start the new engine.
From here I'm not yet sure what should happen in what order:
- re-install the nodes with the old engine to remove the Engine HA Setup from that host.
- re-install nodes on the new cluster to receive the Engine HA Setup.
There is documentation about backup and restore of the engine here:
