One Version service updates overview

The following set of topics provide information that is related to service updates for Microsoft Dynamics 365 for Finance and Operations version 8.1 (October 2018) and later. This is applicable for cloud releases only.

The experience for service updates consists of four distinct steps:

  1. Configure
  2. Notice
  3. Update
  4. Validate

The rest of this article describes each step and provides links to related topics.


Customers can select a maintenance window, based on their business constraints. In Microsoft Dynamics Lifecycle Services (LCS), use the fields in the Production environment update cadence section on the Update settings tab of the Project settings page, as shown in the following image. A calendar of upcoming updates is available to help you plan ahead.

Users must opt in to new features and turn them on. All updates are applied first to the user acceptance testing (UAT) environment and then to the production environment. Therefore, customers have time to do any validation that is required. Customers can select the environment that is updated. They can also pause for a maximum of one consecutive service update.


Release plans will be available to help you plan ahead and understand what is changing. You can learn about upcoming features up to three months in advance. The What's new topics provide details about the updates for specific months.

Additionally, a notification email will be sent five days in advance, and a notification will appear in LCS just before an update, as shown in the following illustration.

After notifications have been sent, Microsoft will apply the update (auto update) during the designated maintenance window. After this operation is completed, a notification email will be sent to indicate the status of the update. Customers will also be able to self-update by using the standard update experience in LCS. For more information, see Apply updates to cloud environments.

Customers who participate in the First release program will have an opportunity to update their sandbox environment and other environments before general availability. To sign up for the First release program, go to https://aka.ms/FirstReleaseFnO.

Customers will also be able to self-update by using the standard update experience in LCS, as shown in the following illustration.

After an update is completed in the UAT environment, a basic business process test can be executed to validate the environment. To support this effort, a no-code automation test tool for business process testing is available, as shown in the following illustration. For more information, see Create and automate user acceptance tests.

Some customers have both external data integrations and internal data integrations. We recommend that these customers use the Data task automation tool for testing.
