While brainstorming about one of our labs, the question was raised on whether you can upsize your VCSA while upgrading to a newer version. Specifically, from 6.5u2 to 6.7U1 (build 8815520 to 11726888). We wanted to upgrade to the latest version but we also believe we had outgrown the original VCSA size that we deployed. VMware has made this really simple. I did a quick test in my home lab, and that is what this post will be based on.
