I sent this message earlier this week via gmane but it seemed to have problems at the time and I did not see the message show up. So I try again. If anyone wants to react you can take your time as I will be on vacation the next two weeks. :)

I went ahead and added an upgradeStep to eXtremeManagement, a project management Product for Plone. The trunk there is meant for Plone 2.5 and 3.0 but some tabs are duplicated in 3.0 so I wanted to fix that. The upgrade step does this. The changeset is here: http://dev.plone.org/collective/changeset/48097 The central piece of code there is the handler that simply runs all steps from an extension profile that I added for this upgrade step: def from_plone25_to_30(context): # Right, context == portal_setup here. context.runAllImportStepsFromProfile( 'profile-Products.eXtremeManagement:eXtremeManagement-30-types', purge_old=False) Does this way of using upgrade steps look sane? Like I said in my previous post, there are two things that I do not quite like about this or that I at least did not expect: - I need to specify a handler even though I only want to run the import steps of a profile, which I now have to do by hand in that handler. - I need to register an upgrade step *and* an extension profile, which feels double to me and which adds another profile to the list of extension profiles, which gets longer and longer. I hope I do not sound too much as only complaining. These upgrade steps form a good foundation. I just feel some parts are missing or have room for improvement. If other people feel the same way I do not mind putting some code where my mouth is. :) Or if I misunderstood how best to use upgrade steps, feel free to enlighten me.
