Can I Upload a config. from a Balance One to a 305?
No, that will not work. You can open a support ticket and we may be able to convert it for you.
You know what It’s not that big of a deal. I was just worried about all my DHCP reservations but I will just manually plug it in to my new 305. Another question, Say I have a 305 and I downloaded the config. and uploaded it to my new 305, will the config. I upload also carry over my DHCP reservations or would I have to manually add them back?
Yes, the DHCP reservations will remain intact in the config.
