Not that I recall. Having said that. Up til and including version 3, Rekordbox was a product developed and produced by Mixvibes. Since version 4 it’s Pioneer’s own development. While I don’t recall redoing anything, it is possible that the software asked when making that move. Since companies usually don’t do major upgrades very regularly, having to re-analyse once every 1 or 2 years wouldn’t be too bad. RekordBox DJ has always been a Pioneer product of course.
Cue & Loop points should transfer over. Beatgrid adjustments might turn out to be a bit trickier. Making a copy of the data first and then trying it out makes good sense. You can always restore the old data in case it doesn’t work the way you like.
On a side note: 30k tracks is a lot and not something we advice here. As a mobile DJ I recognize the desire to have every relevant track every made with me at all times, but it pays to have a small (500-1500 tracks) core collection that you know you could fill every imaginable night with, just having to say no to the requests, but that is still small enough to know intimately enough. There are some posts on the subject, might make for interesting reading.
At the end of the day it’s all about what works for you, of course!
