Hi,
Existing customers with Business Central Premium or Essentials subscriptions purchased before October 1 2020 will keep their existing environment entitlements (three production and three sandbox environments) for a period of one year until October 1 2021 or until their subscription is renewed or ended, whichever occurs last.
Access to two additional production environments during this period won't increase your overall database storage capacity and won't enable extra sandbox environments. These benefits are only activated with the production environments purchased by the customers separately.
Examples:
Your Business Central subscription renews before October 1 2021 - You can use up to three production environments until October 1 2021. After that date, you'll only be entitled to one production and three sandbox environments.
Your Business Central subscription renews after October 1 2021 - You can use up to three production environments until the day your subscription renews. After that date, you'll only be entitled to one production and three sandbox environments.
When your entitlement for two additional production environments expires, the additional production environments you may have created during that period will still be fully available, you will not be automatically charged for the extra environments, but in order to become compliant you will have to purchase additional production environments via your CSP partner within 30 days following the expiration date. See the Exceeding capacity quotas section for more details.
Use the Capacity page to see how many environments of each type you have available for your organization.
