New iMovie won't update previous project and events
Just got a new macmini M1 (running Big Sur of course). I migrated my info from High Sierra. Update iMovie to 10.2.5 I had it update previosu projects, but it did not find most old projects. I hav eto admit that many of those projects have not been opened for many years, some are more than 10 years old, but stil I owudl liek to open them (which I currently cannot). Is there a way to update th eprojects so that the 10.2.5 version can see them (open tehm)?
Mac mini 2018 or later
