Move phase to new parent project and client

User wants to move a project phase to another parent project under a new client. User has successfully moved the phase under the new parent project by changing the Parent Project field on the Settings > Details tab, but the phase is still linked to the old client. How can this phase be linked to the new client?

In order to resolve this issue, you can change the client of the new parent project to some other client. You can create a new client as a placeholder and change the client to the one you need later. Make sure you are applying the change to the phases as well. Note that as you are changing the client for the new parent project in the Projects screen, you will receive multiple prompts. Select the correct options on those prompts and implement the changes to all the projects.
