We are in the process of migrating our 7-mode systems to a cDOT cluster running cDOT 8.2P3 (we will be updating again soon). The 7MTT tool works well however I have noticed it tends to leave some cruft behind. I have created a volume migration checklist that I use for every NAS volume migration that I have performed. If you would like a copy feel free to email me directly and I can provide that to you.
As far as LUN-based volumes go we opted to use client-based utilities such as robocopy to migrate the data to the new LUNs. This option isn't for everybody however we are primarily a NAS shop so there is not much LUN-based data to worry about.

That is what Mark is referring to, unless your comment refers to migrating from one cluster to another. You can not SnapMirror from 7-mode to cluster-mode (clustered Data ONTAP aka cDOT). There is a tool available on the support site called the 7-mode transition tool (7MTT). This does leverage SnapMirror between the two versions but only for the purpose of migration and currently only for file data (CIFS,NFS) not block (FC,iSCSI,etc). There is an appliance used to move block data called a DTA.

Ah, now I understand. and it makes perfect sense. In this situation, we'd probably just snapmirror the data to the new cluster and start from semi-scratch.
