Upgrade from 24.7.9_1 to latest OPNsense

[techgirl45]

Hi, apologies if this is the wrong area of the forum. I have been running OPNsense since 2024 on version 24.7.9_1. It's a great firewall and I run it in Proxmox on an N100 router. I want to upgrade it to the latest version but wasn't sure if there could be any issues with the configuration or the upgrade from such an old version.
I'm using the ISC DHCP client which looks to be a legacy, there isn't really anything else configured right now apart from the basics although I'll probably setup OpenVPN or Wireguard once the Firewall is upgraded.

Thanks!

You are probably talking about ISC DHCP Server I am guessing ?!

I would advise you to migrate to either KEA DHCP Server or DNSmasqd DHCP & DNS Server first and then update!
You can Export all your Static DHCP Mappings into a .CSV file and then Import it again into whatever your choice will be to migrate to ;)

Many thanks for this. I reconfigured it all in the new server and it's working fine now. The Firewall is upgraded now to the latest version so I'm very happy. I'm trying to get OpenVPN working now, tunnel comes up but routing to it seems to be an issue although NAT rules seem fine. Hopefully I'll have it running soon!
