Report SCCM Content Library Package Issue in Side by Side Migration in System Center Configuration Manager (Current Branch) Posted January 10, 2020 I will give background about the scenario, we are in the process of Side-by-Side Migration from SCCM 2012 R2 to SCCM 1906 CB. As per the guideline, I have configured the products classification in the new site identical like the old site and synchronized. Now I am at the phase of the migrating Applications, Collections, ADR, Software Update Package and its deployment. For E.g.: I am trying to migrate Office 2010 Software Update Package and its deployment and it’s all associated collection and rules from SCCM 2012 R2 site to SCCM 1906 Site. Migration is failing and the error was that the destination site doesn’t have software updates with unique id: b2f2052b-d652-4895-bc2e-c5105acadb00, 10756e43-6c49-45c1-a897-12b4e89fdc11 Screenshot for your reference below as i couldnt paste it here I have given below a details screenshot of the error from the Migration manager log: The migration manager is complaining that file lib id b2f2052b-d652-4895-bc2e-c5105acadb00 doesn’t exist in the destination hierarchy so it couldn’t move the Office 2010 package from SCCM 2012 to SCCM 1906. I was looking for this update in the all software update group list. I was even unable to find that software update even in the SCCM 2012 R2 Hierarchy, which means that content_id is invalid and stale. It needs to be removed from the package id so the migration manager won’t look into it during migration Below is the screenshot for location the where all the software update deployment package are: When I open this package id, I was able to find all the references of all software update in it: screenshot given below for your reference: If you look at the screenshot above, the Office software deployment package has the reference of a software member (b2f2052b-d652-4895-bc2e-c5105acadb00) in it, so the migration manager is looking for it the new site. However i have checked Microsoft Catalog to see if the above unique_id is what software update, but even it is not in Microsoft Catalog. I think it is a stale unique Id which needs to be removed from the package. Due to the reference still exist in the Package, the migration manager is not able to migrate the package from SCCM 2012 R2 to SCCM 1906 CB. PS: I have used content library clean-up tool but it freed up only the orphaned contents in the DP. But it didn't remove the stale references from the Package. Also I have validated the package and even redistributed the content again to the DP to see if it fixes the issue. I used t-sql query to find the article Id and title information from in the SQL db, but there is no information. can you guys help me to fix the issue. The main agenda is to migrate all contents from current hierarchy to the new hierarchy.
