Flow & Power Apps Migrator

Have you ever tried moving canvas apps or cloud flows across Microsoft 365 tenants or sites? This is a common task when deploying apps and flows to production. Apps and flows have to be exported, imported and SharePoint actions manually updated. These manual updates are error-prone and labor intensive. Flow & Power Apps Migrator automatically converts exported flows and apps to be compatible with the target environment.

Flow & Power Apps Migrator also helps you migrate SharePoint lists that are used as a dependency for your Apps and Flows. There is an interactive UI form that lets you do just that.

Finally, the Flow & Power Apps Migrator converts SharePoint List Forms customized with Power Apps.

Convert flows, apps and solutions

Export flows, apps and solutions

Export all of your flows:

Export all of your apps:

2. Place exported flows, apps and solutions in the src folder

3. Run Migrate-Packages.bat

The scripts will iterate through all ZIP files inside the \src directory and convert them to be compatible with the new Microsoft 365 tenant or site.

• Run Migrate-Packages.bat script

• Enter source site URL and target site URL:
• Keep MIGRATE_LISTS property set to True if you want to migrate SharePoint lists and libraries.

• Select lists and libraries to migrate

• Sit back and wait for the lists and libraries to be migrated and the conversion process to finish.

4. Navigate to the \dist folder and collect converted flows, apps and solutions

5. Import converted flows, apps and solutions

Now go ahead and import your flows and apps to the destination tenant. All SharePoint actions are now be converted and point to the new location.

Power Apps data sources are all converted

Flow actions are also converted

How it works

Flow & Power Apps Migrator finds all unique IDs pointing to the source SharePoint site and replaces them with the destination IDs. resourceMapping.csv contains the mapping of these IDs.

Limitations

• Does not support macOS and Linux.
• Only SharePoint data sources are updated.

Preparing a deployment package for your Clients and Partners

Prepare-Deployment-Package-for-Client.bat script prepares a deployment package that you can share with your Clients or Partners.

On your end

• Run Prepare-Deployment-Package-for-Client.bat

• Export your Solutions, Power Apps and Flows and save them to the package\src directory

• Send the package directory to your Client or Partner.

On the Client's side

• If not already exsists, create a SharePoint Online site. It will contain SharePoint Lists and Libraries that Power Apps/Flows require.
• Open the package directory.
• Run Convert-Packages.bat script.
• Provide target site URL.
• Navigate to the dist folder and deploy converted solutions, apps and flows that will be compatible with the target environment.
• Import all solutions, flows and apps from the dist directory.

Note: Convert-Packages.bat will:

• Deploy SharePoint lists and libraries (if you chose to do package them)
• Convert Apps and Flows from src and saves them to 'dist'.
