With a Store subscription, can I upgrade to higher level during that year?

If I sign up for a yearly Store subscription, can I upgrade during that year? I know you can't downgrade, but is upgrading an option?

You can upgrade at any time during the subscription period without penalty. The upgrade terminates the terms of the old subscription and triggers the beginning of a new subscription period.

Excerpt below:

You can change your subscription at any time, including:

• Changing your Stores subscription level
• Changing your subscription duration

When upgrading your Stores subscription (changing your Stores subscription level to one with more benefits, or changing from a monthly subscription to a yearly subscription of the same subscription level):

• Fees for your current subscription for the current invoice month are prorated and the unused portion of your current subscription is credited back to you. Your upgraded subscription fee is also prorated for the current invoice month and your upgraded subscription is treated as a new subscription.
• Your free-insertion-fee listing allotment from the plan being canceled ends immediately. (Any unused free-insertion-fee listings from your previous subscription allotment don’t roll over.)
• You receive upgraded Stores benefits immediately. You receive your full allotment of free-insertion-fee listings for the new upgraded subscription immediately. Each calendar month thereafter, you receive the applicable allotment of free-insertion-fee listings.
• Your upgraded Subscription Start Date and renewal date is reset based on the date you change your subscription.
• An early termination fee isn’t charged if you upgrade your Stores subscription with the same or higher subscription duration.
