Changing Microsoft account associated to xbox live account/gamertag

I no longer use the email account I used when I first setup my xbox. I therefore have a gamertag and xbox live account that is associated to a redundant email account.

I have subsequently created a new Microsoft account associated to a new email account. I want the original gamertag, which my son uses regulalry, associated to the new Microsoft account.

Any ideas how this can be achieved?

Thanks for reading.
