Yeah the feature exists on paper at least, but not in principle from my experience.
I switched to iPhone 15 Pro recently from Android and after trying to import my data from Android couple of times and iOS failing to import WhatsApp specifically, I had to resort to buying third party software to perform the message transfer via a Windows laptop.
Bear in mind the import process took like 3 hours each time and I had to keep both phones close to each other, couldn't use them while importing and had to keep power supplied to them.
After about 10 hours of trying, I gave in and put 100$ towards proper third party software to transfer my messages. This is ridiculous, as I have Google Drive on my iPhone with my WhatsApp backups from my old phone, however for one reason or another these backups cannot be utilised by WhatsApp on iOS.
Moving between two Android phones "it just works".
