SnapMirror using ONTAP 8.3.2 to ONTAP 9.8

[YeremiaSionC]

Hi everyone,

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?

*Note, No Intercluster Switch are available.

just to confirm that the 2552 is Clustered ONTAP (cdot). and not 7mode?

Hi,

Existing FAS2552 are using 8.3.2 cDOT version.

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

 obviously a bit more to it. Once over Simplified

The upgrade is a multi day process

 8.3-> 9.1-> 9.3->9.5->9.7->9.8 (add new nodes)

 or

8.3-> 9.1-> 9.3->9.5->9.6 (snapmirror to 9.8)

or

8.3-> 9.1-> 9.3 (reinitialize new unit to 9.7 and snapmirror from 9.3 to 9.7)

 in every case, you should use the most current P release in each version

no more pre-coffee posting for me.    I read that as 8.2.3 for whatever reason.    There's no 7mode 8.3.   

Snapmirror compatibility guide.

you could bump the 2552 to 9.3 and re-init the new one to 9.7.  

I second what TMAC said about using VMware to move the VMs.
