Choice to keep classic gamertag in the future?

i don’t want to change the suffix, i want to change my classic gamertag while keeping the same ‘new format’ gamertag

You actually show as having a classic gamertag and a new gamertag. So some areas will still show the old gamertag (classic gamertag).

I'm trying to change my classic gamertag which is the one you see in games. My classic gamertag got changed and my Xbox One and Xbox App gamertag stayed the same (the Xbox One gamertag is the ones they added with the new gamertag system).

My Xbox One gamertag is different to my in-game gamertag and I want my classic gamertag to be changed. You can only change your classic gamertag on the Xbox One console, I have tried using the other ways and you can only change your Xbox Gamertag, not your
classic gamertag.

The reason I want to change my classic gamertag is that the classic gamertag can be fifteen characters and the Xbox One gamertag can only be 12 characters. If I use the other ways to change my gamertag it limits me to 12 characters and sets both my gamertags
to that.

Hello, My name is David. I am an independent advisor, happy to help you today.

I understand that you would like to align or remove your "modern gamertag" to match your "classic gamertag" on Xbox. Unfortunately, due to certain limitations and restrictions, it may not be possible to achieve the exact desired outcome. Here are a few points to consider:

Character limit: The "modern gamertag" has a character limit of 12, while your "classic gamertag" exceeds this limit. This means you won't be able to directly change your "modern gamertag" to match your "classic gamertag" if it exceeds 12 characters.

Cloning or duplicating gamertags: Currently, there is no feature or option available to clone or duplicate a gamertag from one account to another. Each gamertag on Xbox Live must be unique, and it's not possible to have two identical gamertags associated with a single account.

Removing the "modern gamertag": If you want to remove your "modern gamertag" and keep only your "classic gamertag," unfortunately, it's not possible to remove the "modern gamertag" entirely. Every Xbox account must have a unique gamertag associated with it. However, you can choose not to use or display the "modern gamertag" and primarily use your "classic gamertag" instead.

Best regards.

Not all games have been updated to work with the new gamertag policy. So any tags with a special character will not show a new tag, but your account will keep your old tag as a "classic" gamertag for use in those areas.
