Planning the upgrade

When preparing for the upgrade, take into account the environments that you have in your pipeline. To ensure that the upgrade process goes smoothly, use the following best practices:

1. Start the upgrade process by cloning your staging environment. In this way, you will be able to run the upgrade and test the application afterwards without interrupting other work that is happening in the staging environment.
2. Run the pre-upgrade check on the cloned staging environment.
3. Upgrade the cloned staging environment.
4. Note and resolve any potential issues that occurred during or after the staging upgrade.
5. Upgrade the production environment as soon as possible after the cloned staging environment, to ensure that there are few differences between the staging and production data.
6. After the production upgrade is completed successfully, upgrade any other environment that you have in your pipeline, for example, staging, development, QA, or BOE.
7. Optional: Upgrade your Next-Best-Action Designer in a staging environment and review the performance of your strategies to ensure that they continue to give the expected results. For more information, see Upgrading the Next-Best-Action Designer.
