Deangelo can delete old templates to avoid making a mistake like this again.
delete old templates
Explanation:
Deangelo's company has moved from Portland to Seattle. Generally in such cases, many things change when it comes to the working of the company. May be the company is working for some other cause and has implemented necessary changes in the documentation but couldn't do it in an effective way to begin with.
Deleting the old templates and acquiring new ones will reinforce the fact of the migration of the company and the change of agenda(if any).
