If you want to merge your accounts, the easiest and fastest way is to transfer all projects from one account to another account.

For example, you have account A and account B. You want to keep only one. First, add Account A to all project teams of Account B. Second, reassign all tasks from Account A to Account B. Third, write to support that you want to delete your account A.

  1. If Account A is the Owner of projects, then add Account B to all that projects' teams, next make Account B the Owner of these projects, and remove Account A from the Team
  2. If Account A is a member of Project Teams, then add Account B to all that projects' teams, reassign tasks from Account A to B, and remove Account A from the Team
  3. Check that there are no projects left in Account A (don't forget about the archive!)
