We’re planning to upgrade our production ConfigMgr environment so that we can deploy Server 2012 and Windows 8.1. Currently we have ConfigMgr 2012 SP1 CU3 with MDT 2012 Update 1 and Windows ADK 8.0. We have one Primary site and several secondaries. My understanding is that I need to do the following:
- Upgrade Windows ADK 8.0 to 8.1 (uninstall 8.0, install 8.1 on our Primary site)
- Upgrade MDT 2012 U1 to MDT 2013 on our Primary site
- Install ConfigMgr 2012 R2 on our Primary site
My primary concern with this upgrade is that we are in the middle of our Windows XP to 7 migration. I am using an MDT 2012 U1 integrated deployment task sequence including the MDT 2012 toolkit, settings, USMT, and MDT database.
I am looking for feedback/links/resources/horror stories from others who have already been through this. I would like to minimize OS deployment downtime and plan accordingly for outages. Here are some concerns that I have:
- Will uninstalling/reinstalling ADK have any effect on my existing production task sequence deployments? They use a USMT 5 package from ADK 8.0
- Will upgrading MDT from 2012 U1 to 2013 have any effect on my existing deployment task sequence toolkit, settings, boot image packages etc…
- Are there any “gotchas” with the R2 upgrade that will impact my existing deployment task sequences or any ConfigMgr 2012 components (app deployment, software updates etc...)?
Any advice or links are appreciated. Thanks in advance!
