Hi Maurits, Thanks for the speedy reply!
Hmmm... you make a good point about the ZODB file size. At installation, though, there was a notable difference. The new, default Data.fs was 2.9MB, whereas the mounted, older Data.fs (renamed, of course) was/is 4.4MB. I like your suggestion re: just upgrading though each minor release number. If someone doesn't suggest an alternative, speedier route, then I'll do as you suggest. Thanks!
