We previously had CRM 2011 installed. When CRM 2013 came out we upgraded our deployment to this. We've used it for a few months and have decided it isn't as usable for us. I'd like to downgrade. How do I go about doing this?
AFAIK there is no such thing as downgrade. I'd would say you will have to do a full scale data migration from 2013 instance to a brand new 2011 instance.
