Handle App ID change and configuration migration during major AL extension upgrade

(0) ShareShare
ReportReport
Posted on by 355

Hi everyone,

I need some guidance regarding deployment and upgrade handling in Business Central AL extensions.

I initially developed a customized solution in AL, downloaded symbols, created the extension, and deployed it successfully in the client environment with all required configurations.

Now, there has been a major change in the solution architecture, where the entire code has been migrated to use a new API / different implementation, so I created a new AL package, downloaded symbols again, and completed all code changes.

My concern is this:

If I deploy this new package to the client environment, the App ID is different from the previous extension, so the old configuration/data setup may conflict with the new deployment.

What is the best approach in this situation?

  • Should I keep the same App ID and treat it as an upgrade?

  • If the App ID has already changed, how can I safely replace the old extension without losing configuration/data?

  • What is the recommended way to handle upgrade and migration in Business Central for such major changes?

Any best practices or upgrade strategies would be highly appreciated.

Thank you.
