8. V102 to V103 upgrade procedure

8.1. Prerequisites

To install the V2.5.3.103 update:

  • The GCenter must be running V2.5.3.102-HF3 or higher

  • The GCap will need to be version V2.5.4.0 or higher

  • If you have any questions about these items, please contact the Gatewatcher Technical Support

    Important

    It is highly recommended to have an iDRAC type connection in order to be able to connect post-upgrade if a problem occurs during the process. Otherwise, you'll need a physical access to the equipment (screen, keyboard).

    Important

    Before proceeding with the update, it is strongly recommended to backup the GCenter configuration in the Administrators > Backup / Restore > Operations menu and save the file to an external server in a directory indicating the current GCenter version (example: 2.5.3.102-XXXX-HFX).

8.2. Retained data

All the GCenter configuration and data are retained.
