I have an old, old Live account. Like 2002 old. I had to change the gamertag (same account)...

[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.

I'm not saying that (maybe my english it's not the best). I have and old GFWL account with the gamertag "SrTommy". Now I have a new X-Box Live account with the gamertag "". I would like to delete my old GFWL account so I can change my new gamertag
to my old one.

I had the same problem 2 years ago. I had to change my mexican account to USA and I asked the support for this but they didn't change it. I had to create a new account an start from scratch. Now I want to close my old account to recover my old gamertag and
the support can't close my old account neither.

Each 360 account can be associated with a Live account.

Currently I have:

old 360 account -> associated with my Live account but with the old gamertag

new 360 account -> associated with my Live account but with the new gamertag

The new account got created when I downloaded my profile using my microsoft sign in. The old account was associated with the same microsoft sign in but it didn't recognize my gamertag change. Now it won't let me sign in to live because it asks for my microsoft
sign in details. I'm guessing the sign in fails because it's trying to find the microsoft account associated with the old gamertag.

I either need to somehow transfer my saves over to the new 360 account so I can upload them to the cloud, or I need someway for my Xbox to realize that my gamertag changed on the old account so I can sign into live again with that account.
