In reply to your question as I was in the same boat and since MCC pilot log has become a subscription based log book, I might aswell transfer to logten pro for little bit more, but genuinely 100% better and more user friendly software.
There is some info on logten pro website how to migrate and essentially you only need the export and then import the excel file.
However, I suggest you first edit the columns in the excel file so you can better integrate into Logten pro.
It took me about an hour of editing, importing then deleting again and importing again untill I got the result I wanted.
You can run a log ten pro trial and transfer all your stuff across before you buy anyway so that will give you an idea of what’s involved.
