Help!! - Access opnsense on replacement device

[tre4bax]

After 5 years my opnsense router box died.  Worse I found my configbackus were not good.

I bought a new box and I have a USB adapter for the sata drive from the old box as the drive slots differ.  It boots on this adapter, but I cannot login as my password is very long and complex and I cannot get the box to attach to the network or a device attached to its ports.   I think the configuration of the ports is different so the instance thinks it has no ports.

I tried booting to single use mode and doing opnsense-shell password, but when it reboots it does not remember that password, I suspect because the right part of the disk is not mounted through USB, though I cannot manually mount them.

My goal is just to get a current version of the config from this disk.  Anybody got any ideas how I can do that?  Once I have that I will do a reinstall and import that config.

Well I've made some steps.  Seems when I tried to reload the partition RW after going into single use mode it failed and I did not notice.  Figured it out in the end and manage to change the default password (so i can easily get in) and also copy the whole conf directory onto a usbstick.

Now for the next challenge.
