we had set up Box few years back and had a different domain name then. we had re branded and wanted to change the Box login to the new one.
it did not allow us to do. so had upgraded to business plus plan but even then it was not working.
so have created a new login and uploaded the contents and have bought the business plus plan.
now i want to downgrade the older version to a free version as i do not want to pay twice.
can anyone assist me with this please as to how this can be done.
thank you
