How to migrate from Data ONTAP 8.2.3 7-Mode to Clustered Data ONTAP 8.3

Hello Guys,

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).

 

FAS2240-2 - 24 x 600 GB SAS disks

DS2246 - 24 x 1.2 TB SAS disks 

 

FAS2240-2 - 24 x 900 GB SAS disks

DS4243 - 24 x 2TB SATA disks

 

FAS2552 - 4 x 800 GB SDD disks

               - 20 x 1.2 TB SAS disks

 

Thanks in advance,

Adrian.
