Comment 3 for bug 5283

I had a chat with Curtis and here's a summary of it.

I think there are three db tasks and one code task to ensure no interuption to users:
1. Create a description field in the schema
2. Garbo job to to fill it from homepage_content + \n + team description
3. Update the index pages and forms to use the new field (do not show the old fields if the description is not empty).
4. remove the old columns when the garbo job is complete
5. Remove the old field from the models and templates
