Update and Test a System Image in Isolation

A typical multisystem setup consists of a group of linked production systems (or regions), and a stand-alone development and test system, as shown in the following illustration:

The development and test system has copies of the active system images of all your production systems.

To update and test a current system image in a stand-alone development region

1. Transmit a copy of the active system image that you want to update to the stand-alone development region.

   The development region has a copy of the image you want to update

2. Copy this system image to a new version.

   The region creates another copy but at a new version.

3. Make the required changes to the new version of the system image and test these changes.
4. Transmit the updated system image to the production region where it originated when you are satisfied with the updates you have made.

   The new system image is automatically copied to all affected linked regions.

5. Load the new system image.

   The currently active system image is replaced with the updated version.
