Hi, would it be possible to just migrate with a downtime? 1. shutdown management service 2. shutdown usage service (if running) 3. Dump DB 4. Install new server with same IP 4. Install CS on new host 5. Import db 6. start services

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). paul.an...@shapeblue.com www.shapeblue.com 53 Chandos Place, Covent Garden, London WC2N 4HSUK @shapeblue -----Original Message----- From: Martin Emrich <martin.emr...@empolis.com> Sent: 02 March 2018 14:15 To: users@cloudstack.apache.org Subject: Re: How to move/replace management server?

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
