Hi, Liz
Sorry I didn't respond to this earlier... it's been
crazy.
Assuming you didn't make any changes to the KMNN that
you have, you should be able to delete the old product, then install the new
one. When you delete the product, your KMArticleStore and KMArticles will be
broken (because the ZClasses will be missing). But, when you install the new
version, the class-id is the same, so your instances will start working
again.
As always, though, make a backup of your Data.fs in case something goes
awry :)
These should be undoable changes to the ZODB though. The upgrade should be
relatively painless. The thing I haven't figured out is a good way to upgrade
when you've actually made changes to the product. Maybe there should be one
product that defines ZClass base classes and another that wraps those. You
create instances of the wrapper objects, and make your changes to the wrappers.
That way, you can plug in new base classes without interfering with your
changes. I haven't tried any of that though.
Good luck!

An upgrade to KM|netNews was just released.
Everytime I try to import the file, it says "already exists". Simply renaming
the current product does not help as I then get "Permission Manage... already
exists". I tried renaming those files, but was told that operation could not
be performed on these file types.
Could someone please be explicit about how to
upgrade an existing product in newbie terms?
Thanks in advance, Liz
