There are loads of customers still in planning phase of SCCM 2007 to SCCM (System Center Configuration Manager) 2012 migration. In fact, this is very huge topic and need invest lot of time to study the current environment, plan, test and execute the migration. There are loads of Guides and videos available to help you to plan and execute SCCM 2007 to SCCM 2012 migration. Some of them are noted Here , MMS 2012 and MMS 2013. Other list of of videos are here. Migrations from SCCM 2007 to SCCM 2012 would be much more easier with Adaptiva OneSite.
As first phase of SCCM 2012 migration process, we need to setup/build SCCM 2012 hierarchy. We can’t have an in place upgrade and the only way to upgrade is side my side.
Server Migration – Preparing SCCM 2012 server for migration is first step in the migration process. Second step would be migrating packages, collections etc.. Adaptiva Onesite helps in big way to migrate package and content from existing SCCM 2007 to SCCM 2012 environment. Using ConfigMgr, we can migrate all packages. In the Adaptiva Workbench for ConfigMgr 2012, publish all the packages that that you want OneSite to manage, and Adaptiva clients to preserve in their Adaptiva Client cache after being migrated to 2012. The migration of Adaptive server components are very easy.
Client Migration – Once SCCM 2012 infra is ready and prepared along with Adaptiva OneSite servers, we can start the preparation for SCCM 2012 client migration. The process can be summarized in two steps:
Deploy an Adaptiva workflow to redirect Adaptiva clients to the new Adaptiva server for ConfigMgr 2012.
Upgrade ConfigMgr 2007 clients to 2012.
Any SCCM 2007/Adaptiva client added to the collection created in the previous section will immediately run the workflow, be removed from the SCCM 2007 Adaptiva server, and start reporting to the new Adaptiva server. It is recommended that you deploy the SCCM 2012 client to redirected clients shortly after or as part of this process. The SCCM 2012 client can be deployed using standard methods, or via an Adaptiva Content Push policy which would automate the process end-to-end. The following diagram illustrates the process:
