Migrate fleet of VM's across GCP projects. The script automates migrating VM's identified by a specific regular expression from one project to another project.
For VMs that are hosting stateless applications, this process involves near-zero data loss with minimal downtime.
For stateful applications, downtime is large since you need to stop the VMs beforehand to avoid any data loss in the destination system.
High Level overview of how a VM is migrated:
- Create snapshot of the disk.
- Create an image from the snapshot in the source project.
- Create a VM in the destination project from VM in the source project.
