Moving a GCP instance to another zone is actually much simpler than initially thought. It’s just a single gcloud command.
gcloud compute instances move instance-name \ --zone us-central1-a \ --destination-zone us-central1-b |
A few details about moving to another zone.
- VM has to be running.
- You may get a new internal or external IP address
- Local SSDs are ephemeral, so you can’t move them.
- When moving between regions, you may have to select a subnetwork.
- You may have to change GPUs available in the destination if you use them.
