Transfer of old databases into new ones will happen very easily. There will be an "Import" old database function. I do not have a date for availability yet... when i started working on a new version last year I fully intended for it to be done by now. Sadly I lost my job and had to start at a new company that has me on a project that is requiring a huge amount of time. That said PBv2.0 is coming along quickly. There is a ton done on it so far and I'm trying to spend as much time as I can on it each week. Its offered freely so I cant afford to make it the same priority as other tasks I have that pay the bills
I'd still recommend using the existing version and switching over when the new one releases.
