To upgrade from Pega 8.5 on WebSphere to Pega 8.24.1 on Kubernetes containers, start by ensuring your MSSQL 2016 database is compatible and back up both your database and current Pega application. Prepare your Kubernetes environment by setting up the necessary cluster, persistent storage, and installing Helm. Update the Pega database schema using Pega’s upgrade scripts to accommodate version 8.24.1 changes. Customize the Helm chart with the Pega 8.24.1 container image and configure it to connect to your existing database by specifying the correct connection strings and credentials. Deploy the Helm chart, which will initiate the upgrade process, and monitor the logs to ensure the database schema updates successfully. After deployment, thoroughly test the new setup for functionality and performance, reapply any custom configurations, and validate data integrity. Finally, document the changes and train your team on the new Kubernetes-based deployment to ensure a smooth transition
