Migrating an instance to another project/cloud

The migration of an instance from one project to another one, or to a different OpenStack cloud, can be done using snapshots.

In short the procedure to migrate an instance is the following:

  • Create a snapshot of the instance in the source project, if possible (please refer to the instructions provided at Snapshotting Virtual Machines which also explain what are the restrictions of this procedure).
  • Transfer the snapshot from the source project to the destination one (this was discussed in the previous section: Migrating an image to another cloud).
  • In the target environment boot a new instance from the snapshot.
