How do you upgrade to MR14-1 and keep your config?

Hi, maybe i am missing some bits.

But how do you upgrade fom MR14 to MR14-1 and keep the config from MR14?

I uploaded the new MR14-1 and after reboot the Firewall was gone.
i couldn`t reach the 17.5.14-1 714

I had to visit the company, hooked up an VGA Display and USB keyboard.
The upgrade seems to work, i was able to logon with my admin password.

But all NIC settings had been restored to Factory Defaults (172.16.16.16 with Port E0).

After a reboot i was able to load the old version MR14 711, i tried againg with *boot firmware* (this should take the old configuration to the MR14-1, right)?
Boom again, the NIC has a default factory config.

networkd.log show me this information from yesterday...

INFO ; Sep 05 16:29:51 ; ADMIN ; IP ; address[0] = 172.16.16.16;
INFO ; Sep 05 16:29:52 ; ADMIN ; IP ; IP Command; ip -4 address add 172.16.16.16/24 broadcast + dev PortE0 scope global
INFO ; Sep 05 17:34:48 ; ADMIN ; IP ; address[0] = 172.16.16.16;
INFO ; Sep 05 17:34:49 ; ADMIN ; IP ; IP Command; ip -4 address add 172.16.16.16/24 broadcast + dev PortE0 scope global

So i am back at MR14 711

This release need more time to ripe ..
