What is the minimum release level of the Spectrum Scale 5.0.4 cluster? Is it
4.2.3.X?

We have two scale clusters, cluster-A running version Scale 4.2.3 and RHEL6/7
and Cluster-B running Spectrum Scale 5.0.4 and RHEL 8.1. All the nodes in both
Cluster-A and Cluster-B are direct attached and no NSD servers. We have our
current filesystem gpfs_4 in Cluster-A and new filesystem gpfs_5 in Cluster-B.
We want to copy all our data from gpfs_4 filesystem into gpfs_5 which has
variable block size. So, can we map NSDs of gpfs_4 to Cluster-B nodes and do a
mmexportfs of gpfs_4 from Cluster-A and mmimportfs into Cluster-B so that we
have both filesystems available on same node in Cluster-B for copying data
across fiber channel? If mmexportfs/mmimportfs works, can we delete nodes from
Cluster-A and add them to Cluster-B without upgrading RHEL or GPFS versions for
now and plan upgrading them at a later time?
