One word for upgrade and downgrade (or similar)?

As a software developer, I am working on a project with service tiers, such that a user may opt to switch their current subscription to a tier above or below it. A single module handles both "upgrade" and "downgrade" operations. What would be the appropriate name for this module (as seen on a user interface)?

My Google searches have found a couple of options, the closest one pointing me to this question. I do not think "regrade" is particularly appropriate for this use case.

As used in a menu on the user interface, it would be something like:

• Edit Profile
• [Word] Account
• Delete Account

If possible, I would ask that it be one word.

EDIT: A word or brief phrase that basically means "change payment plan" is acceptable.

Solution 1:

One of the best service-level applications I've encountered is HP Instant Ink for Hewlett Packard wireless printers. The module that allows a subscriber to upgrade or downgrade their plan is called My Plan. When you click on My Plan, you go to a page that provides the options available (Occasional Printing, Moderate Printing, Frequent Printing, Heavy Printing, and Business Printing), with an obvious checkmark denoting your current plan, e.g., Frequent Printing. All you need to do to upgrade or downgrade your plan is click on another plan. So, one possibility would be for you to call the upgrade/downgrade module My Plan and by virtue of intuitive page design avoid altogether the need for a phrase meaning "change payment plan".
