4.1.6 Software Upgrade Execution Overview

Before upgrading, users must perform data collection and system health check procedures in Prerequisite Procedures Overview. This ensures the system to be upgraded is in an upgrade-ready state. Performing the system health check determines which alarms are present in the system and if an upgrade can proceed with alarms.

Please read the following notes on upgrade procedures:

• The completion time for all the procedures shown in this document are estimates. These estimates may vary due to differences in database size, user experience, and user preparation.

• The shaded area within response steps must be verified in order to successfully complete that step.

• Where possible, command response outputs are shown as accurately as possible. Exceptions are as follows:
  • Session banner information such as time and date.
  • System-specific configuration information such as hardware locations, IP addresses, and host names.
  • Any information marked with XXXX or YYYY. Where appropriate, instructions are provided to determine what output should be expected in place of XXXX or YYYY.

• After completing each step and at each point where data is recorded from the screen, the technician performing the upgrade must initiate each step. For procedures which are executed multiple times, the checkbox displayed on the screen can be skipped, but the technician must initiate each iteration as a step is executed.

• Captured data is required for future support reference if a representative is not present during the upgrade.

• Answer these questions, and record:
  • What is the DSR Application version to be upgraded?
  • What is the DSR Application new version to be applied?
  • Is this a Major or Incremental Upgrade?
  • Are there IPFE servers to upgrade?
  • Is SDS also deployed (co-located) at the DSR site?

    Note:

    SDS does not need to be upgraded at the same time.
  • Is IDIH also deployed (co-located) at the DSR site?
