Namaskar Sir,
I am working with 2.1.2 version, presently I want to up-grade my system to 2.5 for that I need your best help.

1. What is the advantage in 2.5 version, comparing to 2.1.2?
2.Can I restore the database captured from 2.1.2 version?
3. Is it necessary to take any specific precaution to install 2.5 version or same principle like 2.1.2?

Expecting your early reply.

Ashok
