1. Open up Exchange Management Shell

2. Change the directory to the Scripts folder located in the Exchange Install Directory; 

Example: CD  "C:\Program Files\Microsoft\Exchange Server\V14\Scripts"

3. Run the following command:

 .\RedistributeActiveDatabases.ps1 -DagName <dagname> -BalanceDbsByActivationPreference –ShowFinalDatabaseDistribution –Confirm:$false
