@ -692,6 +692,26 @@ NOTE: If you have changed the container's configuration since the last start
attempt with `pct start`, you need to run `pct start` at least once to also
update the configuration used by `lxc-start`.
[[pct_migration]]
Migration
---------
If you have a cluster, you can migrate your Containers with
pct migrate <vmid> <target>
This works as long as your Container is offline. If it has local volumes or
mountpoints defined, the migration will copy the content over the network to
the target host if there is the same storage defined.
If you want to migrate online Containers, the only way is to use
restart migration. This can be initiated with the -restart flag and the optional
-timeout parameter.
A restart migration will shut down the Container and kill it after the specified
timeout (the default is 180 seconds). Then it will migrate the Container
like an offline migration and when finished, it starts the Container on the
target node.
