If you're like me and wanting to switch to newer mods that are actively being updated I have the solution for you. In my case I want to switch the Brachi to the ARK additions version and the other 2 creatures into the KBD version. Make sure you have your creatures in a soul ball from the Dino Storage v2 mod and then close ARK (and if you are a server owner, turn off the server.) Once this is done add this to your GameUserSettings.ini.

Or if you'd like to change them to their vanilla counterparts (Brachiosaurus -> Brontosaurus, Styracosaurus -> Triceratops, Aberrant Styracosaurus -> Aberrant Triceratops, Stygimoloch -> Pachycephalosaurus) you could use this:

ConvertClass=/Game/Mods/ARKaeologyDinos/Dinos/Brachiosaurus/Brachiosaurus_Character_BP.Brachiosaurus_Character_BP:/Game/PrimalEarth/Dinos/Sauropod/Sauropod_Character_BP.Sauropod_Character_BP,/Game/Mods/ARKaeologyDinos/Dinos/Styracosaurus/Styracosaurus_Character_BP.Styracosaurus_Character_BP:/Game/PrimalEarth/Dinos/Trike/Trike_Character_BP.Trike_Character_BP,/Game/Mods/ARKaeologyDinos/Styracosaurus/Dinos/Styracosaurus_Character_BP_Aberrant.Styracosaurus_Character_BP_Aberrant:/Game/PrimalEarth/Dinos/Trike/Trike_Character_BP_Aberrant.Trike_Character_BP_Aberrant,/Game/Mods/ARKaeologyDinos/Stygimoloch/Dinos/Stygimoloch_Character_BP.Stygimoloch_Character_BP:/Game/PrimalEarth/Dinos/Pachy/Pachy_Character_BP.Pachy_Character_BP

Once this is done you can just toss the creature out and it should convert.
You can now uninstall the ARKaeology Dinos mod.
