App-V 5.0 – Convert Legacy Packages to the new file format

App-V 5.0 – Convert Legacy Packages to the new file format

Hi all,

In a previous post we showed how easy it is to test App-V legacy packages, now we’re going to convert automatically these packages to the new App-V 5.0 format.

http://blogs.technet.com/b/virtualworld/archive/2012/10/24/app-v-5-0-legacy-package-conversion-report-creation.aspx

To complete this we’re going to use the “ConvertFrom-AppvLegacyPackage” cmdlet from the App-V 5.0 Beta 2 release.

ConvertFrom-AppvLegacyPackage

Converts each package to the new file format. The cmdlet will return all packages that were successfully converted as well as output any errors or warnings found during the package conversion.

Example: ConvertFrom-AppvLegacyPackage -SourcePath "{legacy pkgs}" -DestinationPath "{vnext pkgs}"

First we need to locate the directory that holds all the legacy packages within the Powershell console.

The following can be used:

Cd c:\packages\4.6

Once the console window is in that location we need to specify a directory for the converted packages. To do this we are going to use a variable $50Packages.

$50Packages = "C:\Packages\5.0"

You can create this directory manually but if you want Powershell to create this then you can use the command below.

New-Item -Path C:\Packages\5.0 -type directory

As you can see from the directory structure for the legacy packages in our case “C:\Packages\4.6”, each package has its own folder which contains the package assets. You have a choice here, you can create all the folders manually for the 5.0 packages or you can use Powershell to create them automatically for you.

You may have guessed we’re going to use Powershell to do this.

What the command below is doing is listing the contents of the directory in our case “C:\Packages\4.6”, its then looping through each folder and creating a new directory within the $50Packages variable with the name of legacy package.

dir | ForEach-Object { New-Item -Path $50Packages\$_ -type directory }

Now we have the folder structure created we’re going to go ahead and convert each legacy package and set the output to the new $50Packages directory within the defined folder we created above.

dir | ForEach-Object {ConvertFrom-AppvLegacyPackage -SourcePath $_.FullName -DestinationPath $50Packages\$_ }

What you will see when the packages are converting is the status of the conversion and in each folder the output. Once all packages are complete then it’s time to check the output and then test each package functionality in the new App-V 5.0 format.

Conclusion
App-V legacy package conversion to the new 5.0 format is an easy process as long as you get the prerequisites completed i.e. directory structure for the new 5.0 packages plus legacy package testing.

If you want a report created as part of the conversion then leverage the report creation from http://blogs.technet.com/b/virtualworld/archive/2012/10/24/app-v-5-0-legacy-package-conversion-report-creation.aspx

  • As your script in your previous post for testing legacy packages, it runs without any problem. Simple and effective! Thanks for that!
