Not a problem. 🙂
I totally understand where you're at, I was in a similar spot a few years ago moving to v.7. I had thousands of blocks (partclips, whatever the term of choice) and 1,763 drawings. My head hurts just remembering...
I don't look forward to next time we get a format switch either. I let the .skf count break 2000 before deciding that all new drawings will be done in autoCAD.
If you work someplace with a serious payroll, you can pay autodesk (or at least our rep, i could get the info for you) to convert them all for you. The rate is obscene though, as I recall.
(however, I'd do it for less than 1/2 what we were quoted ;D)
It's a damn shame they can't stick with one format. *shrug*
Anywho, good luck. 🙂
