Migrating applications with too many additional files

Applications that contain more than 1,000 files cannot currently be migrated using the Migration feature due to technical limitations.

We are actively working to improve this experience. In the meantime, you can use the workaround below to successfully migrate these applications.

Workaround

1. Create a Copy of the Application

In the ConfigMgr Console, create a copy of the application:

• Right-click the application

• Select Copy

Optionally, rename the Deployment Type to clearly indicate that it is the copied version. This name will be visible in the Cloud Portal.

1. Create a copy of the Source Content

Navigate to the application’s source content and create a duplicate of the folder.

1. Zip files to reduce the file count

In the copied content folder:

• Compress (zip) additional files

• Keep only the primary installer unzipped

NOTES

• Do not zip the primary installer.

• If using PSADT, do not zip:

  • The PSADT modules

  • The primary installer referenced in the toolkit

This ensures the installer can still be scanned and hashed, which is required for catalog matching.

Example:

1. Update the Deployment Type's content

In the copied application:

• Edit and update the Content path in the Deployment Type to point to the copied content folder

• Once done, save your changes, right-click on your Deployment Type, and update the content to create a new revision of the app

1. Refresh Migration Data

From the Cloud Portal, Refresh the Migration Data.

Once the refresh is complete, the application should now be available for migration.

1. Add Pre-Script During Migration

When migrating the application, add this as a pre-script to extract the zipped files before installation.

If you already have a pre-script configured, update it to include both:

• The extraction logic for the zipped files (should be first)

• Your existing script logic (after the extraction logic)

Make sure both sets of actions are combined into a single script so they run together during deployment.
