 Right. But to do a cutover you have to put either the cluster or the

Taking a snapshot and loading it into a new DB doesn't require an outage.
Restarting Apache HTTPD is <5 sec and then we're done, but your call.
In my testing the upgrade has been unpredictable in length.
 

I did just look through the migration process. It requires setting a new
master password for the cluster. I'll make one up and put it in my own
Bitwarden, but we REALLY need to get that sorted. If you can give me a
budget, I can sort that out.

The migration and upgrade does not require changing or knowning password.  
It's a single drop down menu. It is needed for both phplist and drupal.
