Recover Old Xbox Live Gamertag

[quote user="DarkhavenX666"]

So if I have a VERY old Xbox gamertag from circa 2002 (Darkhaven3) which I have never used on Xbox 360, would I be able to change my current Gamertag (as in, legitimately buy a change for 800M$P) to this old tag?

No. You cannot join Xbox LIVE Gamertags. Unless recovered that gamertag with the Windows Email details to Xbox LIVE and
then paid the 800 Microsoft Points to change the 2002 Gamertag to something else, and then paid another 800 Microsoft Points ot change your current gamertag to the old one.

But all that would achieve would just be changing your gamertag to your old gamertag and that is all. Nothing else would be transfered from your 2002 Gamertag to your 2012 Gamertag, like Xbox LIVE Tenture (number of years on Xbox LIVE). That would all remain
on the recovered 2002 Gamertag.

You need to press the xbox button, the x that is in the middle, and go to the part where the image of your account appears, and put in add new, and then fill with the data of your old account.

I will add this link: https://support.microsoft.com/en-us/help/17875/microsoft-account-reset-or-recover-password

You should just need to press the Xbox Button and go to "Recover Gamertag" (It may say "Download Gamertag"). From there it will request your Windows Live email and password for your gamertag. Enter this and it will recover your old gamertag to your new system.
