Upgrade problem from old version

[tsystem]

Hello,
I was missing a lot of upgrade and today when i try to migrate my conf to last version i  got problems...

I'm starting from 21.1.9
Upgrade to 21.7 and to 21.7.8 works great
but upgrade from 21.7.8 to 22.1 is the problem : i lost all my networks and vlans confs ... 

Maybe it's can come from NICS ?
- dual port 10GbE PCIE Intel X540-T2
- dual ports embeded on motherboard (ASROCK H470M-ITX/AC) : 1 X Realtek RTL8125BG  +  1 X Intel I219-V

Let me know if you have an idea or maybe if i need to upgrade directly to a newer version to avoid problem or some thing else thant can help.

Thanks by advance
