Moving Google Compute VM instances between Networks

Question

Does anyone know how to move an existing VM instance between Google Cloud Networks configured on a project? I know you can specify the Network at the point of creating an new VM, but there doesn't appear to be a facility for changing it once instantiated. Any pointers appreciated! -Paul

In order to move an existing GCE VM instance to a different network, you will first need to delete the VM instance while keeping all its disks (--keep-disks all flag with gcloud command) [1]. Then create a new VM instance with the existing boot disk [2],[3] and attach other disks to the new VM instance if there is any.

All of the above mentioned steps can be done using the Developers Console as well.
