Interbase on HPUX

Greetings ;

Not sure if this is the right group !

We've got several Interbase db's (Version 4.00 )  on an hpux ;
We've got a need to move some of these to Windows/Linux platforms ;
And into either Interbase and/or Sybase ;
( or even Access ) ;

Being a complete novice with ODBC  I need some suggestions !

Thanx
