You can upgrade, downgrade or change plans at any time.
If you are mid your monthly cycle and need an immediate capacity upgrade, then you will be upgraded and charged for the new plan mid cycle but the credits from your original tier will NOT be carried over.
You cannot have 2 simultaneous plans or varying levels of credit capacity.
If you upgrade or downgrade for the FOLLOWING cycle, then you can use all your current credits until the new cycle and plan begins the following month (your billing date will remain the same). Again, the credits from the prior tier will not be carried over into the new plan.>You can make these changes at anytime.
How do I upgrade or downgrade?

Here you will see your subscription status. To upgrade or downgrade, simply press on 'Change Plan' and select the new plan that you want.
