move-system.pl

Moves a virtual system from one host to another

This command allows you to transfer a Xen instance or other supported virtual system from one hosting server to another. It can be useful if the original host is getting overloaded, and you have brought a new host system online to take some of the load.

During the move process, the system specified with the --host flag will generally be temporarily shut down and un-available. All data files will be copied to the new host (set with the --dest flag), modified as needed, and then the virtual system restarted.

By default, the move will be done without shutting down the virtual system if possible. However, you can force a shutdown and restart with the --shutdown flag. In some cases (such as when the source and destination host systems use different directories), the virtual system may be shut down anyway.

If the --allocate-ip flag is given and the destination host system uses a different IP range to the source host (perhaps because it is on a different network), Cloudmin will select a new IP address as part of the move process.

If a system has been already moved manually, the --manual flag can be used to tell Cloudmin to simply update its configurations to reflect the new host.
