At Transferum there are no down-times when it comes about downgrading or upgrading an account.

You can upgrade from 1 GB to 1 TB within minutes.

This can be done in minutes and doesn't affect in anyway the user and its account settings.

All you have to be aware is that when downgrading an account you have to back-up some data from your account,otherwise it will be lost.

Transferum doesn't take any responsibility about the possible loss of data during the downgrading process.
