How to upgrade domain name to 10 years

Few months ago, I bought a domain name through Forumotion in 1 year term.
Now, if I want to upgrade to 10 years term through Forumotion, how I have to do?

Its currently not possible, but its already been suggested.

If its currently not possible, can I upgrade to 10 years term not through Forumotion but through other server for my current domain www.chuviet.net ? (which few months ago, I bought through Forumotion in 1 year term).

No, with the same adress, you can't. Just if you'll cancel your domain name from forumotion and then you'll buy a domain with another adresss, - this, I think, is possible.

All that you can do is transfer your domain name from Forumotion to a different domain registrar. Whether they offer it to you for 10 years or not, that query you can ask them.

Thank you for your quick reply
