Hi team,

I am new in Business central.
I have question regarding extension rollback. Let's say I have an App.1.0.0.0 which have one table with 2 fields. i deployed the extension on my production environment. And i created some records in the table.

Now, I added two more fields in the same table and upgrade my App.1.0.0.1 version. Deployed the extension successfully.
Now, i found that these fields are causing error in my production environment or i don't want these fields. So, i want to uninstall the App.1.0.0.1 and reinstall the App.1.0.0.0. but when i uninstalled App.1.0.0.1 then my records which i have created in the table after App.1.0.0.0 is also got deleted. because i check the box delete extension data while uninstalling the App.1.0.0.1

when i uninstall the App.1.0.0.1 without checking the delete extension data. then we are getting error at the time of reinstalling the App.1.0.0.0 (error: "A newer version of the extension is already installed.").

Can you please help me.
How to rollback previous version of an app without any data loss or any other alternative.

Thanks!

As mentioned, you can't roll back. You need to create a new higher version of your app or extension that reverts the changes you want to undo.

To roll back, create a new version with the original code but a higher version number. This simulates a rollback while preserving data and complying with the upgrade-only model.

Hi, you must add the version number to install and hope the following can give you some hints.

You cannot rollback to the previous version.

What you need to do is to use the code from v1.0.0.0 and increment it to v1.0.0.2.

Publish the new version.

If you introduce a new table or fields in v1.0.0.1, you need to upload with schema ForceSync.

This will delete the table and fields that does not exist in the v1.0.0.2.

Be cautious, because you cannot get back the data that you lost during ForceSync.

Extension Rollback.

To roll back an extension in Business Central without losing data and without running into the "newer version already installed" error, follow these steps carefully:

✅ Goal: Downgrade an Extension (e.g., from 1.0.0.1 → 1.0.0.0) without Data Loss

🔁 Step-by-Step Rollback Process
1. Unpublish the New Version
Uninstall the current version without deleting data:
powershell
CopyEdit
Uninstall-NAVApp -ServerInstance <ServerInstanceName> -Name "<AppName>" -Version 1.0.0.1 -DoNotSaveData
🔸 Do not check the “delete extension data” box or use -Force in a way that removes data.
2. Unpublish the New Version
Now unpublish the newer version:
powershell
CopyEdit
Unpublish-NAVApp -ServerInstance <ServerInstanceName> -Name "<AppName>" -Version 1.0.0.1
3. Reinstall the Older Version
Now, publish and install the older version again:
powershell
CopyEdit
Publish-NAVApp -ServerInstance <ServerInstanceName> -Path "<PathToApp.1.0.0.0.app>"

Sync-NAVApp -ServerInstance <ServerInstanceName> -Name "<AppName>" -Version 1.0.0.0 -Mode Sync

Install-NAVApp -ServerInstance <ServerInstanceName> -Name "<AppName>" -Version 1.0.0.0

⚠️ Important Notes

This works only if your table schema changes are backward-compatible (e.g., fields were added, not renamed or deleted).

Any fields introduced in 1.0.0.1 and then removed will result in orphaned data in SQL unless you handle cleanup manually.

For production rollback, always validate your process in a sandbox first.

✅ Alternative (Safer): Deploy Fix in a New Version
If rollback seems risky, create a new version (e.g., 1.0.0.2) that:

Removes the problematic fields.

Keeps the app at the latest version.

Maintains data continuity and avoids version downgrade errors.

Let me know if you need the exact commands for AL extension packaging or tenant-specific deployment.

Extension Rollback.

In Business Central SaaS, you can't downgrade an extension version directly. To roll back without losing data, create a new version (e.g., v1.0.0.2) with the same code as your original version (v1.0.0.0) but with a higher version number, and remove the unwanted fields. This lets you simulate a rollback safely without uninstalling the extension or deleting data, as SaaS only allows upgrades—not downgrades.
