If he's got a community license, he doesn't have the PCSI/VMSINSTAL kit
but rather a new system image with a bunch of stuff already installed.
He would probably prefer not to set everything up again from scratch.

In theory, if one knew the locations of *all* of the pieces, one could
reverse engineer an older kit and build a new one like it with the new
images and data from an installation.  But there are a lot of things
that could go wrong, depending on what changed between versions.
