Upgrading PGP Universal 3.2.1MP5

Hello.,.

I need some help on upgrading PGP Universal from 3.2.1MP5 to the most current release 3.3.2MP9

1. First is this the most current realease? 3.3.2MP9
2. Can I upgrade directly to 3.3.2MP9 or do I need to upgrade in steps? If so what are those steps
3. If I need to do this in steps, do I need to wait 1 day in between or how long?
4. Do I need to install a new license that matches the versin or will the existing one still work?
5. How hard is this to do?
6. Any documents would be great.
7. Any other info would be helpful.

Thanks

Ronak
