Step 1: Add a seperate cluster that manages the same service in aquilon but is not exposed to the alias
This results in additional managers for the gateway but has no impact otherwise, as the IPs exposed to the internet are still the previous managers
Step 2: Switch the DNS entries to the keepalived IPs of the new managers
After ensuring fallback works as intended, switch the IP addresses behind the aliases to the new managers' keepalived
Future Work
The old managers can be kept as assisting managers with no external exposure or shut off until the new virtualization service is up and running
