User migration to azure

We just tested migrating a small batch of test users to our new Azure tenant.

While migrating the PC/user account was no problem, the fact that people get a completely blank user profile, certainly was a showstopper!!

Many of our users has had their AD profile for years, even a decade and has a lot of individual settings, ways to work, shortcuts, quick links, favorites/browser cached passwords etc. and they loose all that.
Management has currently halted the process due to the protests.

So I am on the lookout for a way to link/migrate the old profile/profile settings, when Azure joining the PC?
