Due to the differences between 7-mode LUNs and cDOT LUNs, I doubt this would be integrated. Are you aware of the DTA for migrating LUNs? It's a device available through NetApp that will permit a transition from 7-mode to cDOT.
Yes it seems it does, but only 64 Bit Volumes are supported, therefore its not possible to migrate from later Ontap 7 Versions. In my case i have the pain with a FAS3210 HA Pair with PAM and this source can not upgraded to Ontap Version 8 for 64 BIT Support 😞
