I have an ongoing project and they have old NetApp FAS2552 currently used for NFS Volume Share and LUN VMware Datastore, customer ask me to do migrate from their FAS2552 which is still using ONTAP 8.3.2 to their new system FAS2720 using ONTAP 9.8 from Factory.
My questions is
1. Could i perform SnapMirror migrate with these 2 far different ONTAP version between ONTAP 8.3.2 and ONTAP 9.8?
2. If we should upgrade the ONTAP 8.3.2 first to ONTAP 9.8 do this causing downtime?
Build a new SVM on the new cluster and storage vmotion all the Vmware data
you will need to update ontap on the older unit to user snapmirror. Looks like a minimum version would be 9.6 but might as well go to 9.8 since it is supported
alternatively if you happen to have cluster switches you could upgrade the older units to 9.8. Then add the new units to the cluster and use volume move to relocate. Still use vmotion to relocate Vmware data
