While you can continue to use your environment with incompatible extensions installed on the current version 27.5, your environment cannot be updated until you resolve the compatibility issues. If you do not resolve these issues within 90 days after the closure of the update period for version 28.4, your incompatible extensions will automatically be uninstalled so that the update can succeed. Please ensure that you've resolved any compatibility issues prior to this date to avoid the loss of functionality that incompatible extensions provide.

Fix the extension error

1. Review breaking changes introduced in version 28.4 and how to resolve them.
2. Make the required changes to the incompatible extension(s), compile the extension against version 28.4, and perform the necessary tests to verify that the functionality is correct.
3. Upload the fixed extension(s) using the Extension Management page in Dynamics 365 Business Central and select the appropriate version for which the updated extension is compatible.
4. Reschedule the update from the Dynamics 365 Business Central admin center.

Uninstall the extension

1. Navigate to the Extension Management page in Dynamics 365 Business Central and uninstall the incompatible extension(s).
2. Reschedule the update from the Dynamics 365 Business Central admin center.
