Networker space requirements 8.2 to 9.0.1 upgrade

Greetings

I am planning on upgrading from 8.2 to 9.0.1 running on CentOS.  I am wondering If I can expect the Client file indexes, the media database or resource database to increase in size dramatically.  I understand the database type is switching from WISS database format to SQLite format.  To summarize, should I expect dramatic increase in size of client file indexes, the media database or resource database. 

Thank you for your time.
