As you might know, in BC16.x and the previous version of Business Central SaaS (before October 1 2020), you can create three production environments and three sandbox environments in one tenant.
But starting from BC17.0, the policy has changed. Each production environment comes with three additional sandbox environments. So you can only create one production environment and three sandbox environments in one tenant by default.
You cannot create more than 1 production environments.
So, how long will the production environments created before October 1 2020 be available?
The following is extracted from Microsoft Docs:
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.
- 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.
