REstoring Backup Files & New ROMs

[pacard]

I am running 6.1 on my TP2 and I have an entire backup using SPB Backup.

1. Once I update the ROM to Sprint's new release (WM6.5), can I import my backup file (even though it was made while I was running WM6.1)? Or do I have to reinstall each cab and redo all my settings?

2. How do I save my current ROM in case I don't like the newest build?

3. Any suggestions before I embark on the upgrade would be MUCH APPRECIATED.

Thanks in advance! I love this forum!
