Two Assert.AreEqual() comparisons, depending on the input value

I want to check for equality between an enum I created and an input value from a file. It should be one of 3 values and in one case, 2 of these values essentially mean the same thing.

enum myEnum { ver1, ver2, ver3};  

The code is simplified a bit, but the meaning is the same. I want to test something like the following:

Assert.AreEqual(ver1, x) || Assert.AreEqual(ver2, x); //Clearly doesn't work, but this is what I'd like to accomplish
Assert.AreEqual(ver3, x);  

To be clear, these values only mean the same thing in the scope of this one test, they mean slightly different things elsewhere, so ver1 != ver2.
