Hello,
I want to upgrade to the newest SME Server version (7.4). I am still running a version 6.5 on my server.

I have few questions:
1) First it is recommended to do a backup. But I am surprised by the small size of the backup file (249Mb). What does the backup file contains? only config and user files? with or without e-mail files? and what about ibays?
2) Can I update from 6.5 directly to 7.4, or do I have to do something else?
3) Are the network cards supported by 6.5 also supported by 7.4?
Thank you for help!
