Hi I am using SCCM 2012 SP1 and want to update AppA_version_1 to the AppA_version_2. At the moment AppA_version_1 is a core application and is installed to all machines via OSD when the machines are built. For this reason we don't have any collections for AppA_version_1.
I have now created a new application for AppA_version_2 and want to test the deployment to a group of machines. As part of the test deployment I want to supersede the AppA_version_1 which we currently have installed.
In the past I have tested supreseding business applications (which are not part of the task sequence and deployed to users not machines) by first creating a test collection, setting the supersedence options and then deploying the superseding (latest) application to the test collection. When I am happy it works OK I deploy the superseding application to the main collection for that application.
I have not had to supersede an application which is part of the task sequence before but I presume I do it in just the same way ? At the moment I don't want to touch the task sequence. I want to test the deployment of AppA_version_2, then release it to all production machines, then update the task sequence so it includes AppA_version_2. What I don't want is to deploy it to the test group but have it automatically update on all production machines.
The reason I ask is that I have read that if you update the Task Sequence with the latest version of your software and this supersedes a previous version, then all of your machines in production will receive the latest version even though it has not been specifically deployed to them. http://www.windows-noob.com/forums/index.php?/topic/8952-possible-bug-in-sp1-cu1-client-applications-that-supersede-others-may-rollout-unexpectedly/
Even though I am not going to update the task sequence with AppA_version_2 just yet, it has got me questioning the testing of the superseded application.
Am I OK to superseded AppA_version_1 with AppA_version_2 and deploy to a test collection (without it updating all machines in the organisation) even though AppA_version_1 is installed as part of the OSD Task Sequence.
Hope this makes sense
Thanks
