Upgrading running servers?

Well, I can only say that I've updated (without restarting) a handful of
images that were running either Seaside or something else using Kom and
have not had any troubles.  In most cases these were images that were
probably not getting but a few hits a minute, but I believe in at least
one case we made changes to Swiki (yes, wiki.squeak.org) and had no
trouble.  Those were very minor changes though if I remember correctly
(just a method or two).

Excellent links, thanks a lot (and to Ramon for writing the blog). Interestingly, the issue of configuration management was one of the ones that I've been thinking about recently too ;-)

Cheers,
