Title: How to actually migrate to a new machine?
Post by: datenimperator on August 30, 2026, 02:59:34 PM
I'll upgrade my machine, so I'd love to move my existing installation. During the last installation of 26.7 I noticed there's an "import config" step during the process. I had created the installation media on a USB stick larger than needed, and formatted the remaining space as FAT32. I also created a path `conf` and placed a backup of my config als `/conf/config.xml` in it.

However, that wasn't recognized, no matter which device I entered.


Regards, Christian

No need really to import things from the start.

Install OPNsense.

Do some initial config on wan and lan so you can access it and the internet

Update

Install the plugins you need

Import the configuration



Make sure you have all the needed config files. The OPN one you can download from GUI, Adguardhome you'll need to scp. Others...similar with Adguardhome.

Thx for that, I do know about the "late import". I'd really like to learn how to get it right first time. Because, if a default DHCP server starts handing out faulty IP addresses, lots of devices are confused. So, I'd need to first start it in a separate LAN, to stop that. After all, getting the config right from the start would make my installation a lot easier.
