I'm thinking about upgrading PressRoom's Press Contact content type; I want to add a new field to its schema. What's the preferred time to make sure migrate old instances of that content type to the new schema? Do I hook into Extensions.Install's install() method? (I'm assuming that contentmigrations has the code for walking the catalog and touching each instance of these objects, but I'm not sure the best point at which to make that option available.)
Are you sure you need a migration at all? If you need a migration, using Install.py's reinstall==True mode may help, but if you're on 3.0.2 you can also use the upgrade-step support in GenericSetup (chapter 19 of my book covers this; I'm not sure where else it may be documented, apart from the GS tests).
