Hi,
I would like to upgrade my Trello account to Business. On my account I have a personal board that I use alone and a project-related board with other members, where I'm an administrator. I would like to use the upgrade only for my personal area and not for the project-related area. Is this possible? Or is the project-related board with all members automatically switched to business when upgrading, which means I would have to pay for all of them?
