Parallel upgrade from version 9.5.0.x to version 10.2.x

About this task

How to upgrade your environment using a parallel upgrade procedure.

This procedure is documented in less detail than other procedures because it is less widely used.

Note: If one or more components are installed on RHEL 9 or later, implement the workaround described in Installation or upgrade fails on RHEL version 9 and later before getting started.

If you are using default certificates in your current environment, before you start the upgrade, ensure you convert the certificates from the .jks to the .pem format and copy them to the workstations where you plan to install the server components and the Dynamic Workload Console. For the complete procedure, see Converting default certificates.
