There is no migration. NCS and LSM don't have anything in common.
A conversion of the DCR export into a format NCS can import is all I expect
In January a version of NCS/PI should become available that has most functionality (that cisco feels is important), that is similar to that of LMS but in its own (surrely different/perhaps better) way.
I have no idea what to expect yet. I just hope for the best.
Cheers,
