Switch to a different Office 365 for business plan
When your business changes, or you need more Office 365 features, you can switch plans.
The easiest way to switch plans is to use the Switch plans button in the Office 365 admin center. However, using the Switch plans button isn’t supported in all situations. In some cases, you might be able to switch plans manually.
When you use the Switch plans button, you're led through the process of buying a new plan that you can switch your current plan to, all users are automatically assigned licenses in the new plan, and your old plan is canceled for you.
In the Office 365 admin center, go to the Subscriptions page, or choose Billing > Subscriptions.
Choose a plan to see the new total cost per month. Be sure to read the key information, then choose Next to check out.
Select Chat now on the Checkout page if you need help.
When you finish checkout, Office 365 takes a few minutes to finalize the switch. You can start using your new subscription right away.
Here's why this can happen:
You're using more than one Office 365 plan. You can only use the Switch plans button if all users subscribe to the same plan.
You're already using Office 365 Enterprise E5, so you already have all the functionality available in Office 365.
When you use the Switch plans button, the plans that you can switch to are displayed based on the services in your current plan. You can only use the Switch plans button to switch to a plan that has the same data-related services, or to a higher version. This ensures that users don’t lose data related to those services during the switch.
Credit checks when switching Office 365 plans: If you pay by invoice, or reach a certain level of cost, a credit check might be required. A credit check can take up to two business days. Users will have full access to their current plan until you switch them to the new one.
