Open Enterprise Server (OES) provides the option of updating an existing system to the new version without completely reinstalling it. No new installation is needed. Existing data such as home directories and system configuration are kept intact. During the life cycle of the product, you can apply Service Packs to increase system security and correct software defects.
NOTE:The OES 24.1, OES 24.2, and OES 24.3 are updates for OES 23.4 and hence the repositories remain unchanged.
