  This section explains how to upgrade Apigee mTLS 
  to Apigee Edge for Private Cloud v4.53.00.
Apigee mTLS is supported on Apigee Edge for
  Private Cloud versions 4.51.00, 4.50.00, 4.19.06, and 4.19.01. You cannot
  use apigee-mtls on versions 4.18.* or lower. 
Before you begin 
Apigee recommends that you perform backups of the Cassandra, Postgres, and Zookeeper services
before you upgrade Apigee mTLS.
Upgrading 
To upgrade Apigee mTLS: 
  Stop all Apigee components, including apigee-mtls, by executing the following
    command:
    
/opt/apigee/apigee-service/bin/apigee-all stop  
   
  Uninstall Apigee mTLS by executing the following command:
  
/opt/apigee/apigee-service/bin/apigee-service apigee-mtls uninstall  
   
  Reinstall Apigee mTLS by executing the following command:
  
/opt/apigee/apigee-service/bin/apigee-service apigee-mtls install  
   Execute the following command:
  
apigee-service apigee-mtls setup -f /opt/silent.conf  
   Start apigee-mtls on all hosts by executing the following command:
  
/opt/apigee/apigee-service/bin/apigee-service apigee-mtls start  
   
  Start the remaining Private Cloud components by following the existing
    
    startup sequence documentation .
    Note:  It may take as long as 3-5 minutes for Zookeeper
      to re-establish its quorum within the mTLS service mesh. This may or may not be of
      consequence depending on how much—or how little—automation is used during the
      restart process. 
   
  Follow the existing
    update/upgrading ordering
    steps  for other components.
