With the release of Cu 8 for AX 2012 R3 the process for doing a slip-stream installation of AX has changed slightly. In the past we released one CU package file that could be used for both slip-streaming and updating. With R3 Cu 8 we now have two different package files, one for doing an upgrade (R3 RTM to the next CU) and an R3 RTM Slip-Stream package file. This often leads to confusion about whether or not you download the right package file and slip-streamed it properly. To help clear up some of this and hopefully make your upgrades to AX 2012 R3 a lot smoother I thought I'd take a quick minute and cover this topic. The steps below are written for R3 Cu 8, however you can use this example same process to slip-stream any individual hotfix into R3 with your new deployments as well.
Because Ax 2012 R3 makes great use of LCS (Life Cycle Services), you will need an account on here to download CU 8 as it only available via LCS.
