Summary

Procedure

1. This step is only for customers running Neverfail Engine versions older then v11.
   If C:\ProgramData\Neverfail-Protected folder doesn't exist on your Active server please create it manually and then open Neverfail Advanced Management Client, go to its Data\File Filters section and use the Add Inclusion Filter button to add an Inclusion Filter from this folder with the following syntax: C:\ProgramData\Neverfail-Protected\**
   

   
   

2. On the machine running Engine Management Service console (EMS), download the latest Engine kit from https://support.neverfail.com/portal/en/kb/articles/neverfail-continuity-engine.
   Note: EMS machine is not a Primary or Secondary node running our core product Continuity Engine. EMS web console is always installed on a separate machine than Primary and Secondary nodes.

3. On the machine running the Neverfail EMS web console, run the downloaded MSI installer to perform an in-place upgrade of your EMS web console.
   
   Note: Step 4 below is necessary only for EMS consoles versions older then v22. In v22 EMS automatically copies the Catalog folder to the Active server in the cluster which then replicated to the Passive(s) node(s).

4. Also on the machine running the EMS web console, go to C:\ProgramData\Neverfail\VAD and locate catalog folder which contains the cli-setup.exe for upgrading Engine locally on each server node. Copy that catalog folder from the EMS console machine to the C:\ProgramData\Neverfail-Protected folder of Active node. This will assure the cli-tools will get replicated by Engine to all of the Passive

5. Start the upgrade process on the Passive server by performing the steps below. 
   

   1. Open a CMD prompt under 'Run As Administrator'

   2. Set the path to C:\ProgramData\Neverfail-Protected\Catalog

   3. Run the command engine-cli-setup.exe upgrade
      

   4. Repeat steps a to c on the Active server
