As I was doing some Service Manager 2012 R2 Upgrades lately, I created a OneNote page which will guide me through the installation process and help me not to forget anything important 🙂 Since this checklist may be useful to other people out there who are upgrading from Service Manager 2012 SP1 to Service Manager 2012 R2, I decided to share it here. You can get the OneNote section file right from my OneDrive Account.
I provide this checklist as-is and cannot guarantee the accuracy or timeliness of information available from the checklist. In addition to this checklist, also check out detailed instructions by Microsoft on how to upgrade your environment to System Center Service Manager 2012 R2.
If you have any corrections or thoughts about improving the list please let me know. I would be happy to update the OneNote file so others can benefit from your knowledge.
