What about having two installations of Vsig in different folders: one that has H8000fw database and the other having Orville database – Possible?
If yes, also to have the two Vsig's running at the same time – Possible?
Should be, but untested, and essentially unsupported.
Will all .sigfiles developed for Orville work on an H8000fw?
There may be some module differences that will cause trouble, but I'd guess that 95% will be OK. Again, because Orville is now so old, it's hard to be more precise.
