Replacing a working system is an operational decision as well as a development project. We examine what works, what blocks the team and what must survive the change before choosing an incremental upgrade or replacement.
Discuss your requirementsIdentify the critical workflows, data model, permissions, dependencies and deployment process. Review the code and recurring failures where access is available. Record strengths worth preserving, not only the issues users report.
Compare targeted fixes, interface upgrades, integration layers and staged replacement. Prioritize by business impact and risk. A full rewrite is one option, not the automatic starting point; the assessment should explain the tradeoffs.
Map old and new fields, identifiers, attachments and historical states. Agree data cleanup decisions with the owners. Rehearse the migration and compare counts, relationships and relevant totals before choosing the cutover window.
Document acceptance scenarios, access changes and the point beyond which rollback becomes difficult. Plan backups, monitoring, training and a period of observation after launch. Record who approves the switch and who responds to a failed transition.
Review the existing application and collect representative workflows and incidents. Agree a prioritized improvement scope.
Implement the selected changes with demonstrations and regression checks against the workflows that must continue to work.
Test migration and recovery, reconcile the result, then release during the agreed window with clear decision owners.
No. The review may identify specific fixes or staged changes that better fit the requirements. Replacement should follow evidence about maintainability and the required workflow.
We assess available exports, formats and data quality. The agreed migration scope should specify retained records, attachments, mappings and validation rather than assume everything can transfer unchanged.
An assessment comes first when the existing code or data is unknown. The estimate follows the reviewed scope, migration complexity, integration dependencies and release constraints.
