I agree that this is a noisy behaviour, expecially if you’re running test applications in the sandbox environment, but that is at the moment… During a tenant upgrade, that extensions are automatically downloaded and installed to the production tenant (service node) and they will never disappear to the end user. When you publish an extension in a production environment the extensions are published withing a global scope. In a production environment, the behaviour is different. Data of every extensions in the sandbox is preserved during the “shift”, so you need only to publish and install again the extensions you need and magically their data will be available again in your upgraded sandbox environment. Saying that, can you see the second image above? There’s also a round box called DATA. Before this shift, the extensions from the original sandbox are unpublished because that extensions will not be available on the new service node.

When Microsoft upgrades the tenant to a new version (CU) the sandbox environment is “moved” to another service node running the new application version. If you publish an extension in a sandbox environment, this extensions is published within the scope of the service node that is hosting the sandbox.

There’s an “hidden” behaviour (recently explained internally by Microsoft) that occours when you publish an extension in a sandbox environment in comparison to publishing the same extension in a production environment.

I wrote a post some months ago by explaining the Dynamics 365 Business Central SaaS tenant upgrade process that Microsoft has in place (you can find it here) but there are some strange behaviours that start appear to partners and that must be explained.Īs you already know for sure, With Dynamics 365 Business Central SaaS customers and partners have now also the possibility to create a sandbox environment by copying also the production data and it’s quite natural that the Sandbox environment itself is becoming a “testing area” for different extensions (I think it’s the nature of a sandbox environment, isn’t it?).Īfter this introduction, now here is the problem: Microsoft is automatically performing tenant upgrades (CU1, CU2, CU3 and so on) and after these upgrades many customers had a sandbox with all their extensions disappeared, while the production environment was correctly ready to go with all the previously installed extensions (no interruptions).īefore the tenant upgrade we had the following situations:Īfter the tenant upgrade, we have the following situation: I saw different tickets and questions related to the title’s topic in the last weeks and I think there’s the need for a clarification.
