I have two FAS2240-2 running 8.2.3 7-Mode, each one has connected a disk shelf (DS-2246 and DS4243) and I want to migrate to Clustered Data Ontap.
I buy a FAS2552 running 8.3P1 and two IOM6 modules. I want to convert this two FAS2240 to DS 2246 and connect all 4 DS to FAS2552.
At this moment FAS2552 has nothing configured, only the management.
Can you help me with the best solution for this scenario (what should I do first, can I use 7MTT,snap mirror, etc..) ? I also have to move the data from old systems to new one (I have a maintenance window).
