Legacy Modernisation for GovTech — UK Specifics
GDS Assessment During Legacy Modernisation
UK government legacy modernisation projects must maintain GDS Service Standard compliance throughout the transition. Challenge: GDS assesses user-facing services — during a strangler fig migration, users may interact with both old and new interfaces simultaneously. Pattern: ensure the new service is GDS-assessed before it receives real traffic; decommission legacy only after new service passes assessment.
Business Continuity During Government System Replacement
Government systems typically cannot have planned downtime during business hours. Legacy modernisation approach: shadow mode (new system processes real transactions but outputs are validated against legacy without replacing it), canary release (1% of users redirected to new system, monitoring for errors), progressive rollout (by user group or region), and instant rollback capability maintained throughout.
Migrating Legacy Government Data with UK GDPR Compliance
Government legacy databases often contain decades of citizen personal data with poor documentation. UK GDPR-compliant migration approach: data mapping exercise (what personal data exists, where, what basis was it collected), DPIA for migration process (temporary processing in migration environment), data minimisation (do not migrate data beyond statutory retention periods), and post-migration verification (all data correctly migrated, legacy data securely deleted).
WCAG 2.1 AA for Legacy System Replacement
PSBAR 2018 requires WCAG 2.1 AA for all public sector websites — legacy systems exempt from PSBAR while they pre-date it may need remediation when rebuilt. Approach: GDS Service Standard assessment requires user research and accessibility testing, so legacy replacement is the natural point to build WCAG 2.1 AA compliance. ClickMasters uses GOV.UK Design System components as the WCAG-compliant baseline for all GovTech projects.
