Thank you for your reply. In response, no the new machine doesn't need to be new, but it does need to be new enough to be supported. Our other limitation is that it does need to be a laptop, as we need to pack all the IT away after services.
I am looking at a device with intel i5 (or AMD equivalent) and 16GB of RAM, is that good enough, or should I be looking at an i7 and/or 32 Gb RAM? Guess you think either will do.
Thanks again.
