Produce Final Upgrade Plan
This is the final step in the planning phase of your Quantexa upgrade. You have now defined your destination, chosen your approach, detailed your scope, estimated the effort, profiled your team, and created a testing strategy. The purpose of this final step is to consolidate all these outputs into a single, formal Upgrade Plan document. This document will be your master guide for the execution phase and the primary communication tool for all project stakeholders. The Anatomy of the Upgrade Plan Document Your final Upgrade Plan document should be structured, clear, and contain all the key decisions and data you have gathered so far. Use the following structure as a template, pulling in the outputs from each of the previous articles in this guide. 1. Executive Summary 1.1. Project Goal: A high-level statement defining the purpose of the upgrade. What is the current version, what is the final target version, and what are the key business or technical drivers for this project? 1.2. Key Outcomes: Briefly list the major deliverables (e.g., "Upgraded Platform to v2.8," "Migration of ETL framework," "Decommissioning of legacy components"). 1.3. High-Level Estimate & Timeline: State the total estimated effort in days and the target completion quarter. 2. Upgrade Strategy & Roadmap This section details the "what" and "how" of the upgrade. 2.1. Target Version: The clearly identified major and minor version for your Quantexa Platform upgrade. This is the output from Identify Your Destination. 2.2. Upgrade Approach: State your chosen approach: Incremental Upgrade or Reset & Rebuild. If incremental, specify the release strategy: Single Go-Live or Staged Go-Live. This is the output from Define Your Upgrade Approach. 2.3. Upgrade Roadmap: Insert the detailed, staged roadmap table you created. This should show the sequence of all major projects (platform upgrades, infrastructure updates, framework migrations) required to reach the target version. This is the primary output from Identify Your Destination. 3. Detailed Project Scope This is the most detailed section of the plan, defining the precise boundaries of the work. It is composed of the tables you built in the Define Upgrade Scope article. 3.1. High-Level Impact Analysis: Insert the "Impacted Components" table (your "heat map"). 3.2. Out of Scope: Insert the table explicitly listing all items that are out of scope. 3.3. In Scope Tasks: Insert the definitive master list table of all migrations, one-off tasks, and tech debt items that are in scope for the project. 4. Effort Estimate & Resource Profile This section outlines the cost and the team required to deliver the plan. 4.1. Effort Estimate: Insert the final estimation table, including the sub-total, contingency, and grand total effort in person-days. This is the output from Estimate The Upgrade. 4.2. Resource Profile: Describe the planned team structure. State that the plan requires an Upgrade Lead and detail the planned team size based on your chosen approach. Note how the plan will leverage a Quantexa Architect/TDO and, if applicable, a Solution Expert. This is the output from Resource The Upgrade. 5. Testing Strategy This section summarizes the plan to ensure a high-quality, stable release, based on the outputs from the Define Testing Requirements step. 5.1. Guiding Principle & Focus Areas: Testing will be risk-based and targeted at the areas of greatest change as defined in the scope (Section 3). The primary focus will be on the components identified as "High" or "Medium" impact, such as ETL and the Mid-Tier. 5.2. Core Testing Activities: The following activities will be performed to validate the success of the upgrade: Testing Pillar Key Activities & Approach Regression Testing Validate batch outputs (ETL, Resolution, Scoring) against a pre-upgrade baseline using the Statistical Profile Testing Framework (SPTF). Manually execute high-value user journey test scripts for the User Interface (UI). Run automated test suites against key API endpoints. Systems Integration Testing (SIT) Perform end-to-end batch runs triggered by the production scheduling system. Verify successful deployment via the CI/CD pipeline, including database migrations. Conduct spot-checks on security and authentication. Non-Functional Testing (NFT) Capture pre-upgrade performance baselines for key batch jobs and API response times. Post-upgrade, execute the same tests to verify that performance has not significantly degraded and remains within acceptable SLOs. 5.3. Multi-Use Case Considerations (if applicable): This plan includes specific tests to validate the interaction between the upgraded Use Case A and the non-upgraded Use Case B, focusing on the shared Centralized Data Source to ensure continued compatibility. Moving to Preparation With this comprehensive plan assembled and approved by your stakeholders, the planning phase is now officially complete. This document is your charter to move into the Preparation Phase. This next phase involves setting up the necessary project structures, environments, and tooling required to begin the hands-on work. Your Upgrade Plan will guide all preparation activities, ensuring the team is perfectly aligned before the upgrade execution begins.Define Testing Requirements
With your scope, estimate, and resource profile defined, the final step in planning is to create a robust testing strategy. The goal of upgrade testing is not to re-test your entire solution from scratch; it is a risk-based exercise designed to build confidence that the upgrade has not introduced any negative impacts and that the platform remains stable. This guide provides a framework specifically for upgrade testing. It should be read in conjunction with Quantexa's High-Level Testing Methodology for a broader understanding of testing best practices. The Guiding Principle: Test Your Scope Your testing effort should be directly proportional to the scope of change you have already defined. There is no need to review release notes or other documentation again; your "Define Upgrade Scope" document is the single source of truth for what needs to be validated. Action: Identify your areas of focus from your scope document. "Impacted Components" Table: This "heat map" tells you where to focus the most testing effort. A component marked with "High" impact requires a more thorough validation than one marked "Low". "In Scope Tasks" Table: Every line item in this table, especially manual migrations and tech debt removal, should have a corresponding test case to validate that the change was successful and didn't have unintended consequences. The Core Testing Pillars Your test plan should be built around three mandatory pillars. The articles below describe how to perform these tests in detail; this section describes what to focus on in an upgrade context. Pillar 1: Regression and Functional Testing Goal: To ensure existing functionality has not been broken by the upgrade. The focus is on validating the outputs and core functions of your solution. For detailed methodologies, refer to the main Deployment Regression Testing and Functional Testing articles. Upgrade Focus: Use the Statistical Profile Testing Framework (SPTF) to efficiently automate the validation of your batch process outputs (ETL, Entity Resolution, Scoring). Pillar 2: Systems Integration Testing (SIT) Goal: To ensure all components of your solution (platform, infrastructure, schedulers, authentication) integrate correctly in a production-like environment. Area Key Activities End-to-End Batch Validate that your external scheduling system can successfully trigger and complete full and incremental batch runs. Deployment & Stability Validate that your CI/CD process can deploy the application services successfully and that any automated database migrations run as expected. Let the services run to ensure stability. Security Spot-check that users can log in via your authentication provider, that API keys function, and that a sample of roles/policies are being correctly enforced. Pillar 3: Non-Functional Testing (NFT) Goal: To ensure the performance, stability, and security of your solution remain within acceptable service level objectives (SLOs). For detailed methodologies, refer to the main Non-Functional Testing Recommendations article. Upgrade Focus: The key is to establish a pre-upgrade baseline for batch runtimes and critical API response times. Your post-upgrade testing should then focus on verifying that there are no significant performance regressions against this baseline. Multi-Use Case Testing Considerations If you are upgrading a platform that hosts multiple use cases, your testing must account for the interaction between them, especially if you are upgrading one use case at a time. Testing Shared Dependencies: If an upgraded use case consumes data from a shared, non-upgraded component (like a centralized data source), you must test to ensure this interaction still works correctly. Testing Upgraded Shared Components: If you are upgrading a shared component itself, it is critical to perform regression testing for all consuming use cases, including those that are not being upgraded in this cycle, to ensure they are not negatively impacted. With a documented test plan covering the core pillars and any multi-use case considerations, you are ready for the final step: Produce Final Upgrade Plan.Planning for Success
