Is my GT swappable?

[VSP]

I bought a GT that came on an account, but I want to move the GT to my main account, but I don't know if the gamertag is swappable. The seller told me it was but someone has the spaced version of the gamertag I bought. Does that mean it's not swappable?

Yes that's correct, it's not swappable bro
