I was thinking of using firebird for my current web site which uses
MySQL and is getting really hard to manage.

I need to be able to work with the database during development on my
Windows machine.

I got firebird 1.5 RC2 I think... and latest version for FreeBSD is 1.
0.2...

Are the DB files completely compatible? Can I just upload the database
to my FreeBSD machine?

Thanks in advance,

Jason
