Hi, the next linstor-client release, which will happen real soon now, contains an updated "dm-migrate" subcommand. You feed it a dump of the drbdmange control volume an it generates a script that you can review and execute. When the release is done, I also push an update to the users-guide (already written, but not public as of now). I tested this thing with all permutations of: 1 to 3 nodes, 1 or 2 volumes in a resource 0 to N-1 (N is #nodes) diskless assignments a drbdsetup option of "every group" (disk, peer-device,...) on the resource. All these resources got created via drbdmanage and then got migrated to linstor via the script created from "dm-migrate". Yes, it worked ;-). And you have zero downtime.
