Hello,
I'm new in Sophos.
I need to install back a previously removed (2 years ago) XG106.
The active FW (#2) was v17.5.13 MR13
The other FW (#1) was v15.5.12 MR12.
I've upgraded this one (FW #1) in v18.0.6 MR6 without problem, and was able to boot on it.
The config was migrated.
Everything was OK.
Then I tried to upgrade the #2 from v17.5.13 to 18.5.5 MR5.
Also OK, and been able to boot on it with the correct config.
Then I've upgraded the #1 to v19.0.1 MR1.
There was a reset to factory settings.
After booting to this v19.0.1, I can't restore a config backup (file without extension) .
And also, I can't import config from a full exported config from FW#2 v18.5.5 MR5.
It took a very long time (more than 20-30 minutes) and after timeout of admin session, factory settings are still there.
I also tried to rollback FW #1 from v19.0.1 to v18.5.3 but also I can't import config (same effect, very long time, and after timeout of the admin session)
What can I do ?
Do I need to configure again manually everything (WAN, LAN, routing, users, ...) ?
Or is there hope to restore full config from a backup or exported file ?
