[Archetypes-users] Preserving content when uninstalling products

[Shashikant P. <sha...@gm...>]

Hi everyone,

I am using Plone 3.0.5 with Zope 2.10.5. I have a genericsetup profile  
that creates some folders (ATFolder type) and a front page (Document  
type) in the site when I install the product. I did that by creating  
directories in my profiles/default/structure and adding  
relevant .objects files etc just like CMFPlone does it.

In order to upgrade the product, I wanted to uninstall and re-install  
through the portal quickinstaller UI in plone (don't know if there's  
another way). But if I uninstall it, Plone wants to delete all the  
folders and all the content inside them. I tried using a '.preserve'  
file like CMFPlone's profile does, but it didn't help.

How do I prevent that content from being deleted on uninstall?

Thanks!
