Why Upgrade Readiness Starts on Day One

[Abhijeet Upadh2]

Many organisations treat upgrade readiness as a project that begins a few weeks before an upgrade. In my experience, upgrade readiness starts the day the first customisation is deployed on the instance.

Every development decision leaves a long-term footprint. Unsupported scripts, modified out-of-the-box components, duplicated functionality, and unclear ownership all increase future upgrade effort.

Architects often focus heavily on delivering today's requirements while underestimating tomorrow's maintenance costs. Yet the true cost of a design decision is frequently revealed years later when multiple upgrades must be completed under tight timelines.

The most upgrade-friendly instances are not necessarily the least customised. They are the instances where customisations are well-governed, documented, and deliberately designed.

Organisations should establish standards around extension points, code ownership, testing strategies, and architecture reviews from the outset. Automated Test Framework should not be introduced years later. It should become part of the delivery approach from the beginning.

When an upgrade arrives, teams should not need to rediscover why a customisation exists or determine who owns it.

Successful upgrades are usually the result of years of good platform discipline rather than months of preparation.

Architects who think beyond the current release significantly reduce risk, effort, and technical debt throughout the platform lifecycle.
