Brian_Coulombe_Disney,  Spot on, this would be a RFE (request for enhancement). I would recommend working with your sales team to have one opened.
Just want to validate what I already assume:  If I have data on cluster A which has snapshots from 6 months ago stored there and I migrate to cluster B, if I migrate the snapshots off A to B, I should still be able to restore as far back as 6 months on B from the snapshots taken on A.  Correct?  1.  Cluster A has 500TB of data, 6 months of snaps. 2.  SyncIQ data AND snapshots to Cluster B. 3.  Snap-restore request is created for cluster B from 4 months ago.  I shouldn't need to go back to cluster A to retrieve the snaps, I should be able to get it restored locally on cluster B.  Correct?  Haven't had this scenario occur before but it did just happen the other day and we pulled it from cluster A because the snaps were not replicated to cluster B.  So if I synciq the snaps from A to B (which is all the same data pointing to the same files) I should have no problem restoring files from snaps as far back as 6 months, correct?
