Yes but it isn’t usually caused just by migration but rather so migration coupled with changing environments.
Changes in the climate are a huge driving factor of this.
Speaking of the Pokémon example, I believe you are speaking of Sinnoh and Johto. Johto is (at least nowadays) a much warmer region than Sinnoh and during the events of the Arceus Legends game, a huge cataclysm happened that is very comparable to driving factors of IRL extinction events. So the migration of Hisui to Johto is not only plausible but actually foreshadowed
I was talking about Sinnoh/Hisui, but the other region I was thinking of was Kitikami (from Scarlet/Violet’s Teal Mask DLC), as white-stripe Basculin seem to show up in the latter’s waterways.
But yeah, migrations between Hisui and Johto might still have happened, considering that Sinnoh still has Sneasel in the modern day, but only the Johtonian subspecies.
