If you do all your projects under one account, but now want to split projects to different sccounts, then this is quite possible to do. First, register one or more new accounts.
If you want to transfer the owned project:
  1. Add a New Account to this project's team
  2. Make the New Account the project owner
  3. Reassign all your tasks to a New Account (even completed ones)
  4. Remove your account from the project's team
If you only want to transfer just project tasks:
  1. Add a New Account to this project's team
  2. Reassign all your tasks to a New Account (even completed ones)
  3. Remove your account from the project's team

    4. Don't forget about archive projects
