You probably ought to shoot Kasey a PM or e-mail and ask him.

At one time, they were still offering conversions from V7 to V8 for ~$50+S&H, but that has been a couple years ago at least (maybe mid-2010 IIRC). You may now be left with either using their "exchange" service or selling your V7 outright and upgrading to a V8/PSR/etc.
