Would this be a nice short note for the Wiki?

Hi!
Took some time to get some hardware to test, but it basically worked
so far (Migrating DB to new host, and setting up an additional MS on
the new host):
* Stop old MS
* cloudstack-configure-databases on the new host
* dump databases "cloud" and "cloud_usage" on old host
* stop database on old host
* import databases on new host
* edit db.properties on old host (db.*.host, db.*.slaves)
* start MS on old host, works fine with the DB on the other host
* configure-cloudstack-management on the new host
* new MS works, too.
Awesome :)
Cheers,

You can force the issue by stopping the all mgmt. servers, setting
the management_server_id of the hosts in the host table to NULL when
setting the old host to removed then restarting the new mgmt. server.
It's generally best practice to keep your mysql and mgmt. servers on
separate hosts to make life easier when moving stuff around (like now).

Hi Martin,
At a high level, what I would recommend doing, is building a new
management host on CentOS7, add it as an additional management
server. Update the 'host' entry in the global settings to point to
the new host. And then mark the original management server as
removed (by setting a date in the removed field in the database).
Thanks, so I basically upgrade from a single-node-setup to a cluster,
wait a day or so for all components to "learn" that there is a new
guy in town, and then remove the old node? Sounds reasonable...
This assumes your database is on a separate VM/host.
The DB is running on the same host, but migrating it should be easy
beforehand.
Thanks
Martin
