This page describes how to upgrade Red Hat Enterprise Linux (RHEL) in a data center from version 6.x to any of the supported versions of RHEL.
To upgrade RHEL, you need to install Edge for Private Cloud in a new data center containing the new version of RHEL, and then decommission the old data center, as follows:
- Set up a new Apigee data center with servers containing the new version of RHEL. See Adding a data center.
- Install Edge for Private Cloud on the new servers, using a silent configuration file that expands on the existing installation.
- Add the servers to an existing cluster.
- Finally, decommission the old data center, as explained in Decommissioning a data center.
