# Cluster resynchronization

If one or more **Replica** nodes are unhealthy or desynchronized, you can resynchronize them with the **Primary** node by following these steps:

1. Go to the **Overview** tab of your cluster.
2. Click on the **Resync Cluster** button.

A confirmation popup will appear to ensure you want to resync your cluster.

**Resynchronization Process**

1. **Health Check of the Primary**:
    
    
    - Before the resynchronization begins, a health check is performed on the Primary node to ensure the process can proceed successfully.
    - **If the Primary is unhealthy**, a warning popup will appear, and the process will stop.
    - **If the Primary is healthy**, the resynchronization process will continue.
2. **Replica Reconfiguration**:
    
    
    - All Replica nodes will be reset from scratch.
    - Once cleared, each Replica will be reconfigured to point to the Primary.
    - A backup from the Primary node will then be restored to each Replica to ensure full synchronization.
