# What happens if I have duplicated projects?

how Mosaic address and merge duplicated projects

Encountering duplicated projects can create inefficiencies and data discrepancies. Mosaic offers a merging service to consolidate duplicate projects, ensuring streamlined management and data integrity.

During the process of merging, Mosaic will:

-   Transfer:
    
    -   Simply moves data from the unwanted Project to the Project to keep.
        
    -   Moving data may result in updates on related entities move to the Project to keep.
        
-   Merge:
    
    -   Combines data under the unwanted Project to the Project to keep if duplicate exists.
        
    -   Data combined to those in the Project to keep are **deleted**.
        
    -   If duplicate does not exist on the Project to keep, data will be transfered from the unwanted Project.
        
-   Create:
    
    -   Creates necessary data to support transferred or merged data.
        
    -   Typically memberships.
        
-   Delete:
    
    -   Deleted without consideration of transfer nor merges.
