12.1.4 upgrade video

I have plan to upgrade my environment (SEPM and SEP clients) to 12.1.4. In my research phase I had found a video that walks the viewer through the SEPM upgrade from 12.1.2 to 12.1.4. (Should of saved it in my favorites, my fault),but now I cant find it. I have done countless searches over the web and within symantec.com. cant find it and I dont think I imaged it either. Has anyone else seen this video? If you have seen it, can you provide a link. Thanks in advance.
