I was under the impression that AFM could not move between filesystems in the same cluster without going through NFS, but perhaps that is outdated. We’ve only used it in the past to move data between clusters. Could someone with more experience with AFM within a cluster comment? Our goal is to keep the same namespace/path for the users (and ideally keep the same filesystem name) by switching all clients to point to new cluster after a subset of (active) data had been migrated.

But for a vanilla Spectrum Scale cluster -. 1) There is nothing wrong or ill-advised about upgrading software and then creating a new version 5.x file system... keeping any older file systems in place. 2) I thought AFM was improved years ago to support GPFS native access -- need not go through NFS stack...?
