We are migrating domains and I need to figure out a way of how add members on the new domain who are already members on the old domain.
For example: membername@firstdomain.com has access to boards on Trello. I send invite to membername@seconddomain.com and when membername accepts the email invite they are logged in to Trello as membername@firstdomain.com (still on the domain we are migrating off of). I had membername logout of their 'firstdomain.com' account and try to login as membername@seconddomain.com and we receive a message stating the account doesn't exist.
Any suggestions as to how I can assist our members with migrating off our old domain and onto a new one?
