You already know that there is no in place upgrade from the old SCCM2007 to 2012 what if you had an existing SCCM 2007 …simply you will build your new SCCM 2012 as we did during the last 9 parts and then migrate you data from the 2007 SCCM.
In Microsoft System Center 2012 R2 Configuration Manager, the built-in migration functionality replaces in-place upgrades of existing Configuration Manager Infrastructure by providing a process that transfers data from active Configuration Manager 2007 sites. Migration can transfer most data from Configuration Manager 2007.
Migration can migrate most objects from Configuration Manager 2007 to System Center 2012 Configuration Manager. The migrated instances of some objects must be modified to conform to the System Center 2012 Configuration Manager schema and object format. These modifications do not affect the data in the Configuration Manager 2007 database.
You can migrate the following types of objects:
· Software distribution packages
· Virtual application packages
· Software Updates:
o Deployment packages
o Software update lists
· Operating System Deployment:
o Boot images
o Driver packages
o Task sequences
· Desired Configuration Management:
o Configuration baselines
o Configuration items
· Asset Intelligence customizations
· Software metering rules
