I know quite a bit about SQL, but try to stay away from questions like
this one since I don't do any database administration (not even
backups). However, I'm pretty certain it is possible ot have 1.5 and
2.0 running simultaneously, they just have to use different ports
(i.e. not 3050 for both of them) and probably be in different directories.
