Doing a backup and restoring some settings manually works.
The last time I tried it was very confusing. When I first read about "new fresh installation", I thought: "install without keeping settings". However, OpenWrt returned an image check failure, even when I did not keep the settings (sysupgrade -n). It was the same type of error (image validation failed) that would happen if I selected the wrong firmware (but maybe with a different content). The only way to install it was forcing the operation, which might also allow an incompatible image to be installed (bricking the device). Please reconsider some form of upgrade path that validates the image and allows the user to upgrade without a force or going back to factory before reinstalling OpenWrt with DSA. Something like "update package foo to version n.m.z or upgrade to 19.07.9 before installing 21.02 for proper image validation". Most users will not be confident to apply a forced installation. >From wiki upgrading to 21.02 page: "Don't worry - If you try to upgrade with the wrong target, sysupgrade will refuse to proceed with an error message like this: Image version mismatch. image 1.1 device 1.0 Please wipe config during upgrade (force required) or reinstall. Config cannot be migrated from swconfig to DSA Image check failed" My experience and the message content indicates that it will show for all migrations from "swconfig" to "DSA" and not only for "wrong target". I tried to start a discussion about it in an email "Usability issues for DSA upgrade" (jun/28) but I got no answer. It would also be great if we could detect a config from a pre-dsa system and restore everything but skipping or renaming DSA relevant files (nework, wifi?) DSA) with a suffix like '.pre-dsa'. DSA is missing a lot of docs. For example: is there a simple, secure way to detect a system is using DSA for a specific switch (or device)? Is it possible to exist a device with two switches and only one of them uses DSA?
