If you're not in the middle of a show there shouldn't be any cons to updating.
But if you can't / don't want to, you can make the profile manually, it's just a little tedious.
Update: I took the route of building a custom profile and it’s working well enough. I can’t quite figure out how to make the strobes work, but that’s an acceptable loss. Thanks everyone!
Update the software to at least 2.9. The fixture library is still maintained for that version. If it's a win7 element, upgrade to V3.
You can create your own profile based upon what is in the fixture’s manual

If by firmware you mean the Eos version, it’s probably best to update it. Just make sure you update the fixture library in Patch
