Hey guys, I am getting lots of conflicting answers from support and documentation, so I wanted to hear how the community is migrating their 7-mode LUNs to c-mode.
Originally support said that that the 7mtt 2.0 would migrate from 7-mode to c-mode, but after trying to start a project it errored out saying my c-mode must be 8.3 (NetApp support still cannot confirm this is supported or not.)
Then I was told to use a SnapMirror Transision Data Protection, I got that setup and it gets through almost all the baseline and then errors out saying 7-mode LUNs cannot be transitioned to cluster mode.
So what is the real story, is the only way to migrate 7-mode LUNs to c-mode to use a host based utility, or wait until I get to 8.3 and then use the 7mtt?
Solved! SEE THE SOLUTION

I perform transition consulting for NetApp Professional Services and I'd like to clear this up for you. Apologies on any conflicting information you have been provided thus far, please private message me any specific case details so we can address that.
You can use 7MTT or a transition snapmirror to migrate a NAS (NFS/SMB) volume from 7-mode to clustered Data ONTAP 8.2.x onwards.
You can use 7MTT or a transition snapmirror to migrate a SAN volume containing LUNs from 7-Mode to clustered data ONTAP starting with version 8.3.
Data ONTAP checks to see if there is a LUN within the volume when it is building the transition snapmirror to ascertain if it is SAN or not.
In order to complete your SAN volume migration, you can use the following methods, listed in order of preference:
More information on SAN transition process & tools is located in section 3 of the Transition to cDOT technical report located here: http://www.netapp.com/us/system/pdf-reader.aspx?m=tr-4052.pdf&cc=us

Thanks for clearing this up.
BTW... I think we have meet a few time while I worked for one of the large online universities in AZ. Yoiu helped us setup some v-series.
