Full upgrade steps

The full upgrade process involves the following steps:

1. Follow the instructions in the INCONTROL for z/OS Installation Guide: Installing to install the current release to use as a test system.
2. Create a second, separate CR system exactly like the first, to use as a production system.
3. Apply the customizations from your previous version to the current release system.
4. Prepare to migrate production from your previous version to the current release system.
5. Migrate production to the current release system.

When you complete the upgrade, you will have three systems:

• the old version
• the current release test version
• the current release new production version
