In the Project > Plan > Schedule page, you can adjust the start and/or end dates for any project that is not marked as completed or unsuccessful in two ways.
Drag either end of the row to the desired date
Click and move the entire row to a new date period.
When you adjust the dates for a project in planning mode using either of the above methods, Synergy’s elastic planning means:
Any affected child phases will adjust to reflect the new project date.
Any child stages will adjust to reflect the new project date.
Any child tasks will adjust to reflect the new project date.
If you are in delivery mode, you cannot adjust the project start and/or end dates.
