Migration & upgrades
When a platform must change, establish a controlled path from readiness to business acceptance.
- Readiness assessment and migration plan
- Interface dependencies and release risks
- Cutover runbook and regression evidence
Platform migration & AMS
Plan the transition, validate business continuity and improve operations after go-live.
INTELLIGENT ENTERPRISE PLATFORMS
Modernise the platform. Keep the business moving.
Linkfields connects migration assurance with Application Management Services (AMS): managed support and optimisation. Start with migration readiness when target options or transition risks are unclear; start with managed support when incidents, releases or ownership need attention.
Baseline the estate, target, interfaces, data owners and release risks. Agree cutover, recovery and acceptance for the platforms in the IEP portfolio; SAP S/4HANA has its own application and technical decisions.

Migration and managed support deliverables
These are engagement outputs. Platform, source/target, deployment and technical responsibilities are agreed before work starts.
Data migration & reconciliation
When records move, make quality, ownership and exception acceptance explicit.
- Source profiling and mapping/cleansing rules
- Rehearsal loads and reconciliation reports
- Controlled cutover and data-owner sign-off
Managed operations
When the platform enters service, agree support boundaries and a governed improvement backlog.
- Service transition and responsibility matrix
- Incident, change and release workflow
- Service report and prioritised improvements
Intelligent Enterprise Platforms
A controlled platform lifecycle
Example engagement pattern: every gate has a named approver. Performance is assessed against an agreed baseline, not a blanket migration promise.
Assess & baseline
Inventory applications, data, interfaces and target options.
- Gate - Approved estate and readiness register.
Design & prepare
Agree scope, data rules, controls and rehearsals.
- Gate - Approved design, mappings and test plan.
Migrate & reconcile
Run test loads and resolve data exceptions.
- Gate - Data-owner reconciliation and exception acceptance.
Validate & cut over
Test business journeys, access and recovery.
- Gate - Accepted regression and cutover/rollback runbook.
Operate & improve
Transfer knowledge and prioritise service improvements.
- Gate - Accepted handover and improvement backlog.

How managed platform support works
Build a managed support model around your business requirements. This is not a published SLA: coverage, service levels, security ownership and exclusions are agreed.
Scope & transition
Agree supported applications, environments and regions before taking responsibility.
- Service inventory and exclusions
- Knowledge transfer and transition criteria
- Agree - Coverage hours, L1–L3 split and escalation responsibilities.
Incidents & problems
Establish intake, prioritisation and escalation around business impact.
- Incident ownership and communications
- Root-cause and recurring-problem backlog
- Agree - Severity definitions, response targets and provider dependencies.
Change & release
Separate routine requests, enhancements and production releases.
- Change approval and release calendar
- Regression, rollback and security evidence
- Agree - Monitoring, access, patching and release responsibilities.
Governance & improvement
Review service demand, trends, risks and improvement priorities with the service owner.
- Service report and review cadence
- Prioritised backlog and acceptance measures
- Model - Managed Service or Dedicated Team, with service levels agreed in the contract.

Reusable IP for a controlled transition
Four IEP accelerators tailored to the agreed platform, tooling and delivery scope. The artefact structures below are illustrative, not client results. Where selected, testoriumz supports continuous testing; Linkworks supports composable applications where ERP/CRM does not fit.

Migration & Readiness
Structure the decisions and dependencies that determine migration scope.
- Estate and dependency checklist
- Readiness register and decision log
- Example - Risk, owner, action, acceptance gate and status.
Regression & Release Assurance
Make critical journeys and release evidence repeatable.
- Risk-based scenario pack
- Results, defects and sign-off record
- Example - Scenario, expected result, evidence and release approver.
Data Migration & Reconciliation
Trace the move from source records to accepted target data.
- Mapping and test-load checks
- Reconciliation and exception reports
- Example - Source/target totals, variance, owner and resolution.
Intelligent Platform Operations
Use operational evidence to guide the next service improvement.
- Service backlog and reporting structure
- Operational checks and runbook outline
- Example - Incident/change trend, decision, action owner and review status.
INTELLIGENT ENTERPRISE PLATFORMS
Secure migration and operational assurance
Review roles and privileged access, control migration-data handling and retain validation evidence. Agree security tests, rollback and recovery rehearsals with Quality engineering and Cyber Security.
SAP S/4HANA application migration is separate from SAP HANA/Basis administration. Scope sizing, availability, backup/recovery and database security to the deployment; validate SAP Cloud ALM and incumbent Solution Manager requirements. Explore Cloud services and the SAP S/4HANA page.
