Detailed description of the Express Upgrade process

The Express Upgrade enables upgrading the IOA environment using the original data base data sets and operational libraries of the old environment (cloned environments are also supported). It reduces the upgrade downtime to seconds and makes the upgrade process much more stable.

Note: Since the New Environment will be connected to the repository data sets and operational libraries of the old production environment during the Express Upgrade process, it is strongly recommended to back up the production environment data sets and site libraries before starting the upgrade process.
