Hi everyone, John Philpott here with a quick tip for you on an issue where applications may get a new content ID after migrating to a new System Center 2012 R2 Configuration Manager Service Pack 1 (SP1) environment.
The Scenario
You are migrating your current System Center 2012 Configuration Manager infrastructure to a new ConfigMgr 2012 R2 SP1 environment. Your original environment includes applications which are to be migrated over to the new environment. To allow for a phased migration, you have set up shared distribution points in the original environment.
The Problem
Once you migrate your applications to the new ConfigMgr 2012 R2 SP1 environment, you find that a large number of those applications have received a new Application Deployment Type Content_UniqueID. This causes clients to not be able to download content in the new environment from the shared distribution point, as they do not recognize the Content_UniqueID.
The Cause
This can occur if the applications that were created had a source directory that didn't end with a backslash (the \ character). This is because in ConfigMgr 2012 R2 SP1, any application created that doesn't have the trailing '\' in its source gets it added automatically.
The Resolution
To resolve this issue, or to prevent it from happening in the first place, from the old site, update the source path to include a trailing ‘\’ on any application that is missing one (or any app that is getting a new Content_UniqueID after migration).
If you have not begun your migration yet, no further steps are required. If you have discovered this issue post migration, after you complete the step above, re-migrate the application using the “overwrite” option.
After these steps, migrated applications will maintain the same Content_UniqueID.
NOTE In ConfigMgr 2012 R2 SP1 and/or ConfigMgr 2012 SP2, content paths will always have a trailing ‘\’ appended. Because of this, this issue should not occur with content created using those versions.
