Is there a way to safely move integrated storage to a new storage class?

When we initially deployed Vault, we chose raft integrated storage but did not define a storage class on GKE.

Is there a way to safely migrate the data from our existing PVC to a new one with a more performative storage class?

On the OS its just a file so you can mount a new storage class, shutdown vault, move the file and either mount the volume where you’re files are or move the files onto the new storage on a new path and update the config.
