Legacy Modernisation for GovTech — UK Specifics
UK Government Legacy Platform Landscape
UK government digital legacy: HMRC's PAYE and Self Assessment systems (COBOL-based — some dating from 1960s), DWP Universal Credit legacy benefits (COBOL + Java mixed), MOD legacy defence systems (classified architectures), NHS National Infrastructure (multiple legacy NHAIS — NHS Administrative Information Systems), and Local Government legacy platforms (Northgate Revenues, Capita Academy, CGI Govconnect). GDS Service Standard driving legacy modernisation: government's goal is "digital by default" — legacy systems that cannot provide digital-first services are being replaced. ClickMasters has modernised 12 UK government digital services.
GDS Assessment for Legacy-Replacement Services
When a government digital service replaces a legacy system, it must undergo GDS service assessment (Alpha, Beta, Live). Legacy data migration: GDS assessors specifically look for evidence that legacy data migration has been planned and tested. GDS service standard Point 17: identify and understand technical, legal, and organisational constraints — legacy technical debt and data quality issues must be documented. ClickMasters GDS legacy modernisation approach: (1) Discovery includes legacy system documentation, (2) Alpha includes data migration proof of concept, (3) Beta includes parallel running (legacy + new), (4) Live includes legacy decommission plan.
GDPR Data Migration for Government Legacy
UK government legacy data migration: most legacy systems contain personal data that pre-dates UK GDPR (GDPR-compliant basis may not have been documented). Data migration approach: (1) legacy data audit (what personal data exists, legal basis for processing, retention period), (2) GDPR-compliant migration (migrate only data with valid legal basis, delete excess), (3) data minimisation (new system collects only what is needed), (4) privacy notice update (new digital service privacy notice), (5) retention schedule (automated deletion in new system). ICO: government organisations migrating legacy systems should conduct a DPIA (Data Protection Impact Assessment) — ClickMasters produces DPIA as part of GDS Discovery.
GOV.UK One Login Migration for Legacy Government Services
GOV.UK One Login: CDDO (Central Digital and Data Office) programme to replace fragmented government identity systems (Government Gateway, Verify) with a single cross-government sign-on. Legacy services with their own authentication: migrating to GOV.UK One Login as part of legacy modernisation. One Login migration: (1) existing users prompted to link their One Login account, (2) legacy user data migrated (email address, preferences), (3) legacy authentication removed. Benefits: users have one login for all government services — reduces friction and improves security (One Login MFA mandatory).

Frequently Asked Questions
Common questions about govtech software development.
How long does government legacy modernisation take?
UK government legacy modernisation with GDS assessment: Discovery (12 weeks — GDS Alpha pre-work, legacy audit, data migration proof of concept), Alpha (12–16 weeks — prototype, user research, GDS Alpha assessment), Beta (20–30 weeks — build, parallel running with legacy, Beta assessment), and Live (Legacy decommission after 3–6 months Live). Total: 48–64 weeks from Discovery to Legacy decommission. Budget: £40,000–£200,000 depending on legacy complexity. ClickMasters: fixed-price for each phase — Discovery price first, build price after Discovery findings confirm scope.
