FAQ  related to Migration of SCCM  from 2007 to config mgr 2012 Configuration Manager

Source:http://blogs.technet.com/b/configmgrteam/

Q1>What versions of Configuration Manage, or Systems Management Server are supported for migration?

Only Configuration Manager 2007 sites with SP2 are supported for migration.

Q2>Why can’t I upgrade my existing Configuration Manager 2007 sites to System Center 2012 Configuration Manager sites?

Several important changes introduced with System Center 2012 Configuration Manager prevent an in-place upgrade; however, System Center 2012 Configuration Manager does support migration from Configuration Manager 2007 with a side-by-side deployment. For example, System Center 2012 Configuration Manager is native 64 bit application with a database that is optimized for Unicode and that is shared between all sites. Additionally, site types and site relationships have changed. These changes, and others, mean that many existing hierarchy structures cannot be upgraded. For more information, see Migrating from Configuration Manager 2007 to System Center 2012 Configuration Manager

Q3.Do I have to migrate my entire Configuration Manager 2007 hierarchy at one time?

Typically, you will migrate data from Configuration Manager 2007 over a period of time that you define. During the period of migration, you can continue to use your Configuration Manager 2007 hierarchy to manage clients that have not migrated to System Center 2012 Configuration Manager. Additionally if you update an object in the Configuration Manager 2007 hierarchy after you have migrated that object to System Center 2012 Configuration Manager, you can re-migrate that object again up until you decide to complete your migration.

Q4>After I migrate software and packages, do I have to use the new application model?

When you migrate a Configuration Manager 2007 package to System Center 2012 Configuration Manager, it remains a package after migration. If you want to deploy the software from your Configuration Manager 2007 packages by using the new application model, you can use the Package Conversion Manager to convert package and programs into System Center 2012 Configuration Manager applications.

Q5>Why can’t I migrate inventory history or compliance data for my clients?

This type of information is easily recreated by an active client when it sends data to its System Center 2012 Configuration Manager site. Typically, it is only the current information from each client that provides useful information. To retain access to historical inventory information you can keep a Configuration Manager 2007 site active until the historical data is no longer required.

Q6>Why must I assign a System Center 2012 Configuration Manager site as a content owner for migrated content?

When you migrate content to System Center 2012 Configuration Manager, you are really migrating the metadata about that content. The content itself might remain hosted on a shared distribution point during migration, or on a distribution point that you will upgrade to System Center 2012 Configuration Manager. Because the site that owns the content is responsible for monitoring the source files for changes, plan to specify a site that is near to the source file location on the network.

Q7>What are shared distribution points and why can’t I use them after migration has finished?

Shared distribution points are Configuration Manager 2007 distribution points that can be used by System Center 2012 Configuration Manager clients during the migration period. A distribution point can be shared only when the Configuration Manager 2007 hierarchy that contains the distribution point remains the active source hierarchy and distribution point sharing is enabled for the source site that contains the distribution point. Sharing distribution points ends when you complete migration from the Configuration Manager 2007 hierarchy.

Q8>How can I avoid redistributing content that I migrate to System Center 2012 Configuration Manager?

System Center 2012 Configuration Manager can upgrade supported Configuration Manager 2007 distribution points to System Center 2012 Configuration Manager distribution points. This upgrade allows you to maintain your existing distribution points with minimal effort or disruption to your network. You can also use the prestage option for System Center 2012 Configuration Manager distribution points to reduce the transfer of large files across low-bandwidth network connections.

Q9>Can I perform an in-place upgrade of a Configuration Manager 2007 distribution point (including a branch distribution point) to a System Center 2012 Configuration Manager distribution point?

You can perform an in-place upgrade of a Configuration Manager 2007 distribution point that preserves all content during the upgrade. This includes an upgrade of a distribution point on a server share, a branch distributing point, or standard distribution point.

Q10>Can I perform an in-place upgrade of a Configuration Manager 2007 secondary site to a System Center 2012 Configuration Manager distribution point?

You can perform an in-place upgrade of a Configuration Manager 2007 secondary site to a System Center 2012 Configuration Manager distribution point. During the upgrade, all migrated content is preserved.

Q11>Can I combine more than one Configuration Manager 2007 hierarchy in a single System Center2012 Configuration Manager hierarchy?

You can migrate data from more than one Configuration Manager 2007 hierarchy however, you can only migrate one hierarchy at a time. You can migrate the hierarchies in any order. However, you cannot migrate data from multiple hierarchies that use the same site code. If you try to migrate data from a site that uses the same site code as a migrated site, this corrupts the data in the System Center 2012 Configuration Manager database.

Q12>What Configuration Manager 2007 hierarchy can I use as a source hierarchy?

System Center 2012 Configuration Manager supports migrating a Configuration Manager 2007 environment that is at a minimum of Service Pack 2.

Q13>What objects can I migrate?

You can migrate the following objects from Configuration Manager 2007 to System Center 2012 Configuration Manager:

  • Advertisements
  • Boundaries
  • Collections
  • Configuration baselines and configuration items
  • Operating system deployment boot images, driver packages, drivers, images, and packages
  • Software distribution packages
  • Software metering rules
  • Software update deployment packages and templates
  • Software update deployments
  • Software update lists
  • Task sequences
  • Virtual application packages

For more information, see Objects That Can Migrate by Migration Job Type

Q14>Can I migrate maintenance windows?

Yes. When a collection migrates, Configuration Manager also migrates collection settings, which includes maintenance windows and collection variables. However, collection settings for AMT provisioning do not migrate.

Q15>Will advertisements rerun after they are migrated?

No. Clients that you upgrade from Configuration Manager 2007 will not rerun advertisements that you migrate. System Center 2012 Configuration Manager retains the Configuration Manager 2007 Package ID for packages you migrate and clients that upgrade retain their advertisement history.
