Stop SQL services
Get cluster resource from powershell
PS C:\Users\Administrator.DOMAIN> Get-ClusterResource "SQL Network Name (sqlclustername)"
Step 2:
Remove checkpoint using below command from powershell
Get-ClusterResource "SQL Network Name (sqlclustername)" | Remove-ClusterCheckpoint -RegistryCheckpoint

Step 3 :
Chage port from network protocals
Step 4 : Repeat above steps on remaining nodes
Step 5 : Add Checkpoints from powershell
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\MSSQLServer"
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\Replication"
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\Providers"
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\SQLServerSCP"
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\CPE"
Add-ClusterCheckpoint -ResourceName "SQL Network Name (sqlclustername)" -RegistryCheckpoint "SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.InstanceID\SQLServerAgent"
Step 6: Now all set. Start the cluster services
