As discussed in the previous blog, the package content does not get migrated, only the metadata.
During the migration SCCM 2012 clients can still use the SCCM 2007 DPs to locate content.
You can select such DPs by using “Share Distribution Points”.
How does this work?
Well, all DPs will be gathered, also boundaries associated with these DPs will be migrated. So in case of protected DPs, you are safe.
Stuff you need to take into account regarding Shared DPs.
- the SCCM 2012 site server needs at least read access to this location.
- a requirement is that no other Site System roles exist, only the DP role.
- note that this does not work for boot images and App-V content.
In a later phase the DPs can be upgraded to SCCM 2012 DPs.
Now content gets migrated to SCCM 2012, meaning Single Instance Content Store. So no duplicated files will exist anymore on your SCCM 2012 DPs.
Last but certainly not least we have to talk about collections. As you might know subcollections are not supported anymore in SCCM 2012. So how will the migration tool handle SCCM 2007 subcollections?
When subcollections are discovered, the parent collection will get inclusion and exclusion rules to re-establish the relationship between the child collections. A folder will be created to keep the administrative overview.
The migration tool will automatically create organizational folders for all collections that don’t have any members or collections membership rules specified in SCCM 2007. Such collections were basically created in SCCM 2007 to have an administrative overview.
So SCCM 2012 will replace them with folders and create an inclusion rule for the corresponding collection.
In this example is “Brussels” included into “Laptops Europe”
Note, as discussed in an earlier blog, Collections with “limit to” queries to mulitple collections will not be migrated but the migration tool will identify them for you.
So I think I have touched “high-level” all the involved steps and topics regarding a SCCM 2007 \ SCCM 2012 migration scenario. Next time I’ll talk about…… don’t know it yet so stay tuned!
