There are some Pokemon (Cubone, Mankey, Chansey, Pinsir, Eevee, etc.) in Yellow Version with movesets different from those of their counterparts in Red. For example, Charizard doesn't know Fly until Yellow, and Eevee knows Quick Attack earlier in Yellow compared to Red as well as knowing Growl in Yellow. So, if I trade a Charizard with Fly from Yellow to Red, will Pokemon Red be okay or crash?
Just a thought.
This is just a guess, but if the granddaddies (aka. gen 1) works the same as I remember then as long as there is data for the move in question in the game it should be fine. Growl, for instance is a Gen 1 move. It should, in theory, work and not crash your game if you have it on say a ditto or something. As long as the move existed in the generation which you're trading to it should work. There may be questions of whether or not a move or moveset on a pokemon is 'legal', like the aforementioned growl on ditto, but that concern only really matters if you plan on taking it into competitive. If you just want it in your game than it shouldn't be a problem as long as the data exists in that game to make that thing exist. Hence why you can create 'hacked' pokemon like a lvl 1 Dragonite. It's certainly illegal but it shouldn't really crash your game.
