Planning a migration with 2 HA pairs on 7-mode to 2 separate switchless clusters. Vast majority of source data is SAN LUN (Exchange, SQL - which uses SnapManager snapshots). Cust has indicated the preserving the 7-mode snapshots is a MUST. I don;t believe this is possible using any of the migration tools. I was leaning on using 7MTT 2.0, but notice there is a caveat of Snapmanager snapshots from 7-mode not being preserved. Other than the 7MTT 2.0, no other solutions exsist. My strategy if this is the case is to ask the customer to let the snapshots age out (5 day retention) as this may be the only choice.
One final caveat. a 3rd Cluster is to be configured, thats a 3210 HA pait that will act as their snapmirror cluster (intercluster relationship). If we must go to 8.3 for the data clusters, will 8.2 work for the 3210 cluster, as that is not suppoeted with 8.3.
Anyone in the field familiar with this scenario - SAN LUN migration ans keeping snapshots from 7-mode to cDOT.
