Upgrade pfHacom nano -> pfSense
- 
 Hi, As there is now a vga version of pfSense, can I use the Upgrade option to move from a 1.2.3 version of pfHacom to 2.0 version of pfSense. Or would I be better off backing up my config, and doing a clean install. Cheers.

 Always backup your config. ;) If you have a backup you can try upgrade and if something went wrong, you have all possibilities to restore your firewall.

 You should be able to upgrade that way, but backups are always ideal.
