This was somewhat done for Destiny 2, when they moved from Battle.net to Steam (so like the Bethesda situation mentioned in another reply). I'm sure it was a bit easier for them since the base game went F2P which obviously hasn't happened here for Diablo 4, but all of my purchases/DLCs for the game were transferred over to the Steam equivalents.
I'd assume if they really wanted to, they could find a way to just give everyone who has it on BNet a key to the Steam version, but there's no real incentive for them to do that.
I'm a long term Guild Wars 2 player and when they joined Steam the client auto logs you in using your Steam account. However there is a switch you can add so that it logs in using a non-steam account.
Can I transfer my license to a steam one?
Never heard of this for a game tbh
Bethesda did it when they shut down the Bathesda launcher, but other than that it's not really something that happens.
Stardock games were like this.

Doubtful.
