A lot of years ago now, but CAA accepted my (decade previously) UAS Bulldog hours to a JAR PPL(A) just after the new licence came in and I was moving from a microlight PPL to "group A". Both as total hours and logged instruction - but I still had to obviously have logged all of the individual bits of the syllabus.
I don't have time to look it up, but I'm pretty certain that there's something to that effect in LASORS.
