Hello Everyone
Need a help with one our storage refresh project . We have a Primary Array (A) and secondary array (B) which currently all volumes in cluster A is replicating to B via snapmirror.
We want to refresh the both A and B with new A1 and B1 clusters , what is the best way to this to have min downtime and also being able to resynch snapmirror from new cluster A1 and B1 after the upgrade instead of initializing snapmirror from the base snapshot again.
I can rehost the volume from old SVM in old Array A to new SVM in Array A1 and resynch the snapmirror with Array B but this needs downtime (vol rehost) , but when I snapmirror volumes from array A to A1 and then try to resynch A1 to B I get error since ontap can't find the common snapshot.
Thanks for your help.
