I am looking to upgrade from 8.3.1 to 9.3.1. When I started looking at some of the information for 9.3.1 it states that a boot drive of 8GB is recommended. Currently I am running 8.3.1 off a 2GB flash drive so I went out and bought a nice new 32GB flash drive. As I am installing the new version on to a new drive it appears that I need to download the full ISO so that my process would be:
- Download and burn full ISO
- Backup config file from current version
- Shutdown and swap flash drives, put in ISO disc
- Install 9.3.1 from ISO disc onto new 32gb drive
- Restore config file
- Open beer
