Step 4. Upgrade the WebServer Stack

CTE080 – Apply LANSA Application Upgrade to all Web Server Instances

1.  Once you are certain that the DBWebServer upgrade has completed, then repeat steps 1 to 3 for the WebServer Stack, whether or not you have instances currently running in that stack. All new instances will install the MSI last set in the template. So it's important to set it even when the WebServer stack is empty of instances.

2.  Even if you do not RDP into the instance to check the installation status, it is highly recommended to check the CPU utilization of the EC2 instance and ensure it's returned to near zero. This ensures that the database upgrade has completed. Only then may you continue with the process.
