And is there any risk in doing so ? Can I corrupt the ODS10 database ?
(Lee Jenkins seems to think "yes" in the thread "Accessing a IB6 db from FB
1.5")

I need to organize the upgrade from IB6 to FB15 of a mono-user application
that's used by computer illiterates.

Ideally I'd like to do the following :

- Setup installs fb embedded and remove anything related to IB6
- Setup installs new version of the app
- App forces a backup and restore of the db at first start.


Instead of the more tricky :

- *Ensure* the user backed up its db *before* any setup is run
- Setup installs fb embedded and remove IB6
- Setup installs new version of the app
- App forces a restore of last backup at first start.

Thanks.
