[Zope-dev] help: updating zclass-based products

[Heiko Stoermer]

Hi,

we have a development server and a production server.
I'm currently developing a zclass-only product.
To install it on the production server, I make a zexp off my dev-machine
and import it on the prodcution server.

This works _once_, because if I try to import a new version of the same
product zexp, I naturally get an error, as the product is already
installed.

I can delete the old version and re-import the new version of course but
with my zclasses being some kind of static superclasses of their
instances, what happens to these?
Answer: as long as the zope process is running between deleting the old
version and importing the new one, everything's fine.
But if zope dies for some reason, all my instances are gone !?

So: how do YOU update zclass-based products between a development and a
production server?
Can it be that there's no intelligent mechanism for that?
Am I just too stupid?

Thanks,
Heiko
