We have an ASG 220 appliance with firmware version 8.311 with 2GB RAM and plenty of available disk space.
the appliance protects our web servers for which we desire a minimum of downtime.
Up2Date shows an option to upgrade to UTM 9.
my questions are:
1) is it safe to upgrade?
2) what is the expected downtime?
3) do I need to backup and restore my configurations or is that now done automatically by Up2Date?
TIA!
