So, you could leave 3.5.x on your PC and download and install 5.5.x on your Mac. Your dongle is blasted with 5.5, and you can use it on any Mac or PC running any version of MC 5.5.x and lower. If you UPGRADE, then you keep your current serial number (dongle).

Procesor 2 x 2.66 ghz dual core intel xeon

So i would end up switching between the two but doesnt 5.5 require windows 7? Here are the specs and i would like recommendations on what to upgrade included a larger raid if possible-Thanks for all your help in advance

I started to upgrade the xw8200 but with it being down with very sensitive files in it I can not take the chance of it not working again. When I upgrade from xpress pro I kept the dongle so I would just have to move the dongle correct. My question is can I keep the avid on the original xw8200 and then load the Avid on the mac and upgrade from there? It will still have windows xp on it. I am thinking of keeping the xw8200 as it is and upgrade the mac. It's time to replace the xw8200 but the only way I can do that it through an upgrade. The old gal has been a workhorse and with only two sticks of ram it's a miracle that it runs at all. We ended up dismantling the wall and I now have a couple year old mac. I work in government video and Apple built a video display wall for us.
