It's a relocation with some asterisk smudging in there. Just as the Ravens and the Browns1.0 are really the same team well actualies be damned, the Yotes/Yeti (hey, I just realized that's barely a name change...) are one team.
Keeping stats and history is just a nice nod to locals. In ten years from now if Arizona has a team again, those fans are going to care way more about the Yotes history than Utah fans will, just as Jets fans cared more about the original Jets than the Yotes fanbase did, or the Wild fans caring more about the North Stars than the Stars fans did, or the Ravens fans caring more about the Baltimore Colts than Indianapolis Colts fans did, etc., etc., regardless of name and history technicalities.
Fanbases are built off memories, and those memories aren't transferrable from one fanbase to another. Name changes should be mandated any time that a team relocates out of a market for that very reason, imho. Nobody batted an eye when the Jets were in an outdoor game and their old timers games were original Jets players, after all. That's because they were celebrating Winnipeg hockey history. Baltimore Colts alumni routinely are at and celebrated at Ravens games, as to basically a T they've all told Indianapolis to pound sand.
