[DUG] RAD 2007 to what

[Charlie]

Hi, real quick I've wanted to be a programmer for 20 years but "LIFE" 
dictated something else. However I did develop a couple of applications 
and am now being asked if I want to work on one of those app again. So 
I'm seeking y'alls advise as I have done over the years.
The app will be used by 3 users, originally developed with Delphi 2007 
Professional with the BDE & dBase files. Since the computers that are 
now being used are all Windows 8 what should I do:
1) upgrade or not. If so to what release & version eg XE5/Professional?
2) what database to use
3) any gotchas in upgrading?
4) would anyone want to "mentor" me if I take on this project? And if so 
what are your fees"

Thanks
