Migrate Virtual Server
Posted by Andrew Smith on 07/03/16 11:51

OnApp allows hot and cold migration of virtual servers between compute resources that share common data stores (or data store zones). Hot migration means moving virtual servers that are running, while cold migration means moving virtual servers that are shut down.

To check if your Windows template supports hot migration, see

To hot migrate a virtual server:

  1. Go to your Control Panel's Virtual Servers menu.
  2. Click the label of the virtual server you want to migrate.
  3. Click the Tools button and press the Migrate Virtual Server link.
  4. In the window that appears, choose the target compute resource from the drop-down menu.
  5. Move the Cold-migrate when hot-migration fails slider to the right if you want to apply cold migration in case of hot migration failure.
  6. Click the Start Migration button.

After migration, the power status of your virtual server remains the same as before the migration. If you migrate a virtual server that's running, the whole process is almost unnoticeable. 
OnApp administrators can control user access over virtual server migration. Using OnApp permissions, you can allow/forbid users to perform migration of all virtual servers, or their own servers only. This is handled via the Control Panel's Roles andSets menu.
