Users with the “Edit Project Ownership” permission are able to transfer projects from one user license to another. This is useful for moving quotes off of inactive licenses.
Use the User filter on the left to filter down to projects owned by that user. Select the project(s) you wish to change so that they are highlighted.
For multiple projects, either: hold CTRL while selecting projects, hold SHIFT and select the top and bottom of a block of projects to select them all or use CTRL + A to select all quotes.
Right click any of the highlighted projects and click “Change Project Owner”
Use the dropdown box to choose the new owner.
