Estimate The Upgrade
With a clearly defined scope document in hand, you are now ready to build a reliable effort estimate. This process translates your detailed list of tasks into the person-days required to complete the project, forming the bedrock of your final upgrade plan. This guide provides a practical, bottom-up estimation process. It should be used alongside the official documentation's guide on Key factors impacting upgrade effort, which provides essential context on what makes an estimate go up or down. The estimation method you use will depend directly on the Upgrade Approach you selected earlier: Incremental or Reset. Estimating an Incremental Upgrade For an incremental upgrade, the most reliable estimate is built from the bottom up. You will estimate each individual line item from your "In Scope Tasks" table, which you created during the "Define Scope" phase. Action: Build your bottom-up estimate. For each task, estimate the development and unit testing effort. This detailed breakdown ensures you account for every specific migration and change required. To help with this process, detailed Work Breakdown Structure (WBS) templates for specific platform version upgrades can be requested from your Quantexa contact. Task / Migration Description Category Dev Effort (days) Unit Testing (days) Total (days) Upgrade Document Service response handling Manual Migration 3 1 4 Execute database schema update One-Off Task 0.5 0.5 1 Refactor deprecated custom-function-x Tech Debt 2 1 3 Run Repository Tool for v2.7 migration Automated Migration 1 2 3 ...add all other tasks... Sub-Total X Y Z Action: Validate your estimate with the top-down model. Now, use the best practice estimation approach from the Documentation Site as a sense-check. Start with the baseline (e.g., 8 days) and adjust it based on the key factors. Does your detailed, bottom-up total roughly align with the top-down adjusted baseline? If they are close, you can have high confidence in your number. If they are far apart, it's a crucial signal to review both your detailed estimates and your understanding of the influencing factors: Have you underestimated the complexity of a required migration? Have you overestimated the negative impact of your customizations? Action: Add contingency and formal testing. Finally, add a contingency buffer to your sub-total to account for unforeseen issues. Remember, this estimate is for the development and unit testing effort only. The effort for formal testing cycles (SIT, UAT, OAT) must be estimated and added separately. Estimating a Reset A "Reset" project is estimated in much the same way as a brand-new Quantexa implementation. The focus is on estimating the effort required to selectively re-implement the desired functionality in a new, clean repository. Action: Estimate the "re-implementation" effort for each functional block. For each major component of your current solution (e.g., Entity Resolution, Scoring), estimate the effort to build it in the new target version. When doing so, you must factor in the effort to align with modern best practices and to remove the technical debt you identified in your existing customizations. Functional Block Re-Implementation Effort (days) Notes Data Ingestion & Parsing 15 Includes refactoring 3 custom parsers. Entity Resolution 20 Involves re-implementing logic to align with new best practices. Scoring & Alerting 10 UI & Document Views 12 Includes rebuilding 2 custom document viewers. ...add other functional blocks... Sub-Total X As with the incremental approach, a healthy contingency should be added to this sub-total, and formal testing should be estimated as a separate line item. ⚠️Warning: Avoid the "Big Bang" Trap A reset upgrade provides a tempting opportunity to tackle other major platform migrations at the same time (e.g., historical Fusion or Assess migrations, Parsers v4). While this can be efficient, be extremely careful about letting the scope balloon. The effort to validate major functional changes, combined with the cost of a very long-running project, can quickly become unmanageable. It is often better to treat these as separate, subsequent projects.Define Your Upgrade Approach
Having created your Upgrade Roadmap, the next critical decision is to define how you will execute the work. There are two fundamentally different strategies for upgrading your Quantexa platform: the Incremental Upgrade and the Reset Upgrade. This page will guide you in selecting the right approach for your specific context, considering factors like your roadmap's complexity, your solution's health, and your team's capacity. At a Glance: Comparing the Approaches Approach Key Characteristic Best For... Primary Benefit Key Consideration Incremental Upgrading through each major version sequentially ("hopping"). Solutions that are well-aligned with Quantexa best practices and are only a few versions behind. Efficiency. Maximises automation using the Repository Tool. The Repository Tool is less effective on solutions with high technical debt. Reset Creating a new, clean repository on the target version and migrating code selectively. Solutions that are many versions behind or contain significant technical debt. Clean Slate. An opportunity to remove technical debt and realign to best practices. Higher initial manual effort to set up and selectively migrate logic. In-Depth: The Incremental Upgrade This is the most common and efficient approach. It involves upgrading your existing repository through each major version between your current state and your target destination. For example, moving from v2.5 to v2.8 would involve separate, sequential upgrades to v2.6, v2.7, and finally v2.8. This approach makes maximum use of Quantexa's Repository Tool, which is designed to automate much of the migration effort between sequential versions. This is the default and recommended option if you are only upgrading a single major version (e.g., from 2.7 to 2.8). When performing an incremental upgrade across multiple versions, you have two release strategy options: Option 1: Single Go-Live Perform each version "hop" in quick succession within your development environment, but combine them into a single release package. This package goes through one cycle of SIT, UAT, and Production deployment. Benefits: Reduced Testing Overhead: One round of formal SIT/UAT saves significant time and effort. Faster Time-to-Target: Achieves the final goal of deploying the target version in the shortest overall project duration. Developer Efficiency: Developers build deep expertise by performing the "hops" back-to-back, increasing speed. Option 2: Staged Go-Live (Release per Hop) Treat each version "hop" as a mini-project. You develop, test (SIT/UAT), and release each incremental version to Production before starting the next hop. Benefits: Lower Risk per Release: Each deployment is smaller and more contained, simplifying testing and root cause analysis if issues arise. Incremental Value: End-users can benefit from new features and improvements more regularly. Increased Flexibility: Allows your team to address other business priorities between upgrade stages. In-Depth: The Reset Upgrade This approach involves creating a brand-new, empty repository on the target platform version. Your team then selectively migrates or completely rebuilds the required logic (data interfaces, Entity Resolution, Scoring, etc.) from the old repository into the new one. This is a strategic choice to "pay down" technical debt. Benefits: Your implementation is multiple major versions behind the latest Quantexa Platform release. The current solution contains a high degree of technical debt, making an incremental upgrade complex and risky. You need to make significant architectural changes or re-align to modern Quantexa best practices. While this approach requires more upfront manual effort, it ensures that your repository is clean, modern, and optimized for future scalability and smoother upgrades. How to Choose Your Approach Your choice will depend on the specifics of your Quantexa deployment and the goals of your upgrade. If your solution is well-aligned with best practices and your Upgrade Roadmap involves only one or two hops, the Incremental approach is almost always the best choice. If your solution suffers from significant technical debt or your Upgrade Roadmap spans many major versions, the Reset Upgrade approach offers a powerful opportunity to reset for the future, even if the initial effort is higher. Quantexa's Divergence Tool can help provide insights into how far away from best practice the deployment is in certain areas The output of this step is a clear, documented decision on the approach you will take. Action: State your chosen upgrade approach. Example: We will follow an Incremental Upgrade approach with a Single Go-Live release strategy.
