Hello Pawar!

All native Domino databases (designed by IBM) are compatible from 8.0.1 to 9.0.1.
Regarding your applications developed internally and/or by a third company, you should validate it before migrate/upgrade.

The document below has a lot of information regarding the upgrade (steps, links to download, etc;):
