Upgrade Plans

This section describes the ongoing and maintenance activities that are required to keep the system operational, efficient and up-to-date after deployment. It also involves regular checks and updates to maintain the system reliability.

Prerequisites

Ensure the following activities are carried out in a timely manner to maintain the service continuity during the upgrade process:

  • Monitoring: Set up monitoring post-upgrade to track the performance of the upgraded services.
  • Backup: Ensure that a complete backup is taken before performing any upgrade to prevent data loss.

Info

  • OPS Logging Storage Maintenance: Review and manage the 2.1 T logging storage periodically (capacity: 2 days of logs). Add more storage if required to store long-term logging data.
  • Storage Management: Ensure Ceph and Postgresql clusters have enough space for agent data load.

The following services are planned for upgrade, including the necessary configurations and supported platforms:

1. Kafka Upgrade

Upgrade Bitnami Kafka from version 20.0.0 to 28.2.5.

Ensure compatibility with existing configurations and services.

2. Backing Service Configuration Upgrade (PostgreSQL Operator (PGO)/Ceph)

Configure upgrades for PGO and Ceph.

Ensure the latest versions of PGO and Ceph are compatible with the deployment environment.

3. OSS Initialization

Execute OSS initialization auto-script for PGO ALL and Ceph.

The script will automate initialization, including database setups and configurations required for the OSS environment.

4. Database Read-Write Separation Configuration for IoT PGO Cluster

Configure read/write separation for IoT PGO cluster.

Implement a read-only and read-write configuration to optimize the database performance for IoT applications.

5. Upgrade Secret (mdsp-secret-infra-credentials)

Add UTS PGO keys, IoT read/write PGO keys and rename other keys.

Update the secrets used for authentication and ensure that they are aligned with the updated service configurations.

6. Running OSS Check Tool

Run OSS check tool to verify the status of backing services.

The OSS check tool will validate that all the backing services, including PGO and Ceph are functioning as expected after the upgrade.

7. Upgrade Insights Hub Core Services

The upgrade will include updates to core components like authentication, data processing and analytics services.
