Perhaps you could create a backup file first and then try vanilla OpenWRT.
That way, if you encounter any issues afterward, you can always switch back later
Thanks for the suggestion. I already have a backup of the config files.
However, that is not the intent of my post.
To clarify - I want to hear from anyone who has installed OpenWrt 25.12 and how was that experience. Did the upgrade go smoothly and if not then what kind of issues they encountered.
