Like Mike, and I am sure many others, I have also skipped far more releases than I have installed. (I won't try to list what I skipped, I think the list I have installed is: VM/SP 3, 5, 5-HPO, VM/ESA 1.0, 1.1, 2.2, 2.4, z/VM 4.2, 4.4).
In any case, the question "can you go from X to Y" does not seem appropriate to changes in VM, since they are basically new installs every time. There is the subject of spool file compatability, what release will still be able to read the spool files of the old system, but other than that (which has never bothered me, since I do not believe in using spool as alternate file storage) I don't know what difference it makes who X and Y are.
