# How to merge Phases on Project Schedule Modal?

Learn how to merge phases, remove duplicates, and streamline project management for better organization and tracking.

Merging Phases combines two Phases into a single, unified Phase. This feature is particularly useful for eliminating duplicate Phases that may have different Phase numbers or names due to typos. By consolidating tasks and removing redundancies, the Project Schedule becomes more streamlined, improving management and progress tracking.

1.  Click the three-dot on the phase you want to merge and delete, then select **Merge w/Phase**.
    
    > **Info:** Only Phases within the same Project and at the same level as the selected Phase can be merged. Milestones cannot be merged.

2.  Click **Select Phase** to select the Phase to merge into. Click the **Merge** button.
