[Grok-dev] Migrating catalog indexes

[Kevin Teague]

If you've got an Indexes, such as:

class MyIndexes(grok.Indexes):
    grok.site(MyApp)
    grok.context(gsc.haystack.interfaces.IContent)

    created = grok.index.Field()

And it gets grokked, then a catalog and a field index will be created.
But then if you add a second field index:

class MyIndexes(grok.Indexes):
    grok.site(MyApp)
    grok.context(gsc.haystack.interfaces.IContent)

    created = grok.index.Field()
    modified = grok.index.Field()

This index doesn't get created. Soooo ... what's the best way to
migrate a catalog when the indexes are updated after the initial
creation. Anyone got any tips here?
