Upgrade to 2.2 Eventually?
I did a quick search for the answer to this but didn't find anything… Once 2.2 is officially released, will it be possible to "upgrade" from 2.1 to 2.2? Or is it different enough that we won't be able to do a seemless upgrade (having to manually recreate all the settings by hand)?
You didn't find anything because there's nothing to find. We've always supported upgrading from an older release to a newer release and this time is no different. The only exception to that rule was transitioning from the old embedded to NanoBSD style embedded, but since you couldn't do an in-place upgrade on the old style embedded that was a bit of a moot point.
