Plan for Migrating from a Previous Version of App-V
Use the following information to plan how to migrate to App-V 5.0 from previous versions of App-V.
Migration requirements
Before you start any upgrades, review the following requirements:
If you are upgrading from a version earlier than App-V 4.6 SP2, upgrade to version App-V 4.6 SP3 first before upgrading to App-V 5.0 or later. In this scenario, upgrade the App-V clients first, and then upgrade the server components. Note: App-V 4.6 has exited Mainstream support.
App-V 5.0 supports only packages that are created using App-V 5.0, or packages that have been converted to the App-V 5.0 (.appv) format.
App-V 5.0 SP3 only: If you are upgrading the App-V Server from App-V 5.0 SP1, see About App-V 5.0 SP3 for instructions.
Running the App-V 5.0 client concurrently with App-V 4.6
You can run the App-V 5.0 client concurrently on the same computer with the App-V 4.6 SP3 client.
When you run coexisting App-V clients, you can:
Convert an App-V 4.6 SP3 package to the App-V 5.0 format and publish both packages, when you have both clients running.
Define the migration policy for the converted package, which allows the converted App-V 5.0 package to assume the file type associations and shortcuts from the App-V 4.6 package.
Supported coexistence scenarios
The following table shows the supported App-V coexistence scenarios. We recommend that you install the latest available updates of a given release when you are running coexisting clients.
| App-V 4.6 client type | App-V 5.0 client type |
|---|---|
App-V 4.6 SP3 |
App-V 5.0 |
App-V 4.6 SP3 RDS |
App-V 5.0 RDS |
Requirements for running coexisting clients
To run coexisting clients, you must:
Install the App-V 4.6 client before you install the App-V 5.0 client.
Enable the Enable Migration Mode Group Policy setting, which is in the App-V > Client Coexistence node. To get the deploy the .admx template, see How to Download and Deploy MDOP Group Policy (.admx) Templates.
Client downloads and documentation
The following table provides link to the TechNet documentation about the releases. The TechNet documentation about the App-V client applies to both clients, unless stated otherwise.
| App-V version | Link to TechNet documentation |
|---|---|
App-V 4.6 SP3 |
|
App-V 5.0 SP3 |

Converting “previous-version” packages using the package converter
Before migrating a package, created using App-V 4.6 SP3 or earlier, to App-V 5.0, review the following requirements:
You must convert the package to the .appv file format.
The Package Converter supports only the direct conversion of packages that were created by using App-V 4.5 and later. To use the package converter on a package that was created using a previous version, you must use an App-V 4.5 or later version of the sequencer to upgrade the package, and then you can perform the package conversion.
For more information about using the package converter to convert a package, see How to Convert a Package Created in a Previous Version of App-V. After you convert the file, you can deploy it to target computers that run the App-V 5.0 client.
