I have been working with a client using Trello. I set up a workspace in my account and invited them as an admin to the boards in the workspace. I am not renewing my contract with them and want to transfer ownership of the workspace and/or boards to them. I removed myself from the boards and I can no longer see them. However, the workspace still shows up in my sidebar. If I delete the workspace from my account, will it delete the boards the client can see in their account? If so, how do I transfer the workspace to the client to remove the workspace from my account?
