The Migration Wizard in CM is fairly straightforward, and will help us migrate almost all objects from CM07 to CM. Now that we have migrated classic packages, it's time to take advantage of the new Application Model for deploying software. The Creating Applications and deployment types recipe walked through the process - we could simply follow that same process to recreate each of the classic packages into applications. This would be a bit of a time consuming manual process. To streamline this process, Microsoft created the Package Conversion Manager (PCM, a throw-back acronym to the Package Command Manager of SMS 1.2). We will walk through the analysis and conversion process in this recipe.
Note
PCM is not supported in CM 12 SP2 or later, however, we have found a workaround, do test it well and use it at your own risk: http://blog.configmgrftw.com/package-conversion-manager-and-configmgr-r2-sp1-or-sp2/.
