Factory reset after firmware upgrade?

[after]

Hello, I have a RT-AC86U with firmware version 386.11. I would like to upgrade to 386.14 and my question to you is:
- It is mandatory coming from .11 to .14 to do a factory reset? I have a lot of settings that I would like to not do them manually again....
Thank you!

No.

Thank you, should I anyway save the configuration or some screenshots? Could it be the risk after the upgrade to lose some settings or no?

Upgrade to Asuswrt-Merlin 386.13 instead. Version 386.14 was built on never released as official firmware base, you'll lose Wi-Fi Radar, will get nag screens for not needed user agreements and perhaps have to update some of your scripts. All this is not needed at the end of support for this router, IMO.

Done, I have upgraded to 386.13_2. No issues so far, everything looks good. Thank you!
