Let’s quickly note the On-Premises release schedule. Normally On-Premises updates come after online updates with a nearly 6-month delay. You need to apply those updates manually to your environment.

Please check the On-Premises updates page for more details.

HOW TO APPLY UPDATES FOR THE ONLINE VERSION

In this section, we review the best strategy to apply updates. We review strategies for small to middle-complexity customizations. For very complex environments, it is reasonable to get personal advice.

So, if you’re using very basic Dynamics 365 functionality and do not have an organization or person supporting your tenant – you can just schedule updates in Admin and solve problems on production if they occur.

This is, however, not the safest choice. For more complicated cases, I recommend creating a Sandbox environment and opt-in for early updates. You need to create a copy of your production environment to Sandbox, apply updates, and check if everything works smoothly.

Note: Please be careful with integrations. In case you have some, there is a risk that if you change something on the Sandbox – it will be integrated into other production environments. For this reason, Microsoft automatically disables logic on Sandbox initially.

After checking the main functions your organization uses on Sandbox – you are safe to apply them for production.

HOW TO APPLY UPDATES FOR ON-PREMISES

For On-Premises installations, all updates should be applied manually. You’ll need to set up a separate environment to test it. I recommend checking even minor updates for On-Premises. There are some cases when you need to act proactively. I mean feature deprecation.

Deprecation by itself does not mean that the feature is removed right away. It means that the feature will be removed in the next major release after deprecation is announced, giving customers little more than 6 months to adopt it.

For more complicated cases, Microsoft announces feature removal several releases before its actual removal, so customers have enough time to prepare.

Here is a link in the description with a list of deprecated features. Let’s go there and check if your organization will not be affected.

As for now, there is one big change coming on 1st October 2020 – the Old Web Client Interface will be removed, and users will only be able to use a new Unified Interface.
