RESOURCE_OPERATION_RATE_EXCEEDED error appears
RESOURCE_OPERATION_RATE_EXCEEDED error occurs when the source platform of a migration
is Compute Engine and you exceed the limit on disk snapshots when migrating a
Compute Engine VM.
As part of the migration, Migrate to Containers creates a snapshot of the disk images from a VM running on the source platform. You can only create a disk snapshot at most once every 10 minutes, or 6 times an hour, for a Compute Engine VM. This error indicates that you have exceeded that limit.
To avoid hitting this limit, we recommend that you create the migration cluster in the same zone as the Compute Engine VM. When the cluster is in the same zone as the VM, Migrate to Containers can clone the disk, rather than create a snapshot, which is a more efficient process and bypasses the snapshot limit.
