Cloud Hosting Models for LN
LN cloud migration options range from infrastructure-as-a-service lift-and-shift to Infor's fully managed multi-tenant CloudSuite. Each model carries different implications for customization support, operational control, and cost structure. The choice between IaaS, Infor single-tenant cloud, and Infor multi-tenant depends on your customization footprint, integration complexity, and operational maturity.
- IaaS lift-and-shift: migrate LN VMs to AWS, Azure, or Google Cloud with minimal application changes
- Infor single-tenant cloud: Infor-managed infrastructure with dedicated LN instance and full customization support
- Infor multi-tenant CloudSuite: shared platform with Infor-managed upgrades and limited customization scope
- Hybrid model: LN core in Infor cloud with on-premises satellite systems for shop floor and edge processing
- Cost comparison: IaaS typically 20-30% cheaper short-term but single-tenant offers lower 5-year TCO with managed services
Migration Assessment Framework
A cloud readiness assessment must evaluate four dimensions: customization compatibility, integration architecture, data migration complexity, and organizational readiness. Customizations are the highest-risk factor because Infor's multi-tenant platform restricts certain 4GL customization patterns, DLL extensions, and direct database modifications that on-premises LN deployments commonly use.
- Customization inventory: catalog all 4GL modifications, DLLs, custom reports, and VRC packages by cloud compatibility
- Integration mapping: document all point-to-point and middleware integrations with cloud connectivity requirements
- Data assessment: evaluate database size, data quality, archiving candidates, and migration timeline constraints
- Organizational readiness: assess IT team cloud skills, change management capacity, and business stakeholder alignment
- Risk scoring: classify each customization and integration as cloud-ready, needs modification, or must be re-architected
Phased Migration Execution
Successful LN cloud migrations follow a phased approach that reduces risk through incremental validation. Phase 1 establishes cloud infrastructure and connectivity. Phase 2 migrates non-production environments for testing.
Phase 3 executes production cutover with rehearsed rollback procedures. Each phase includes defined entry criteria, validation gates, and go/no-go decision points.
- Phase 1: provision cloud infrastructure, establish VPN/ExpressRoute connectivity, configure identity federation
- Phase 2: migrate development and test environments, validate customizations and integrations in cloud context
- Phase 3: conduct full cutover rehearsal with timed steps, data migration validation, and user acceptance testing
- Phase 4: production cutover during planned maintenance window with pre-staged rollback procedures
- Post-migration: 30-day hypercare period with dedicated support team and daily health check dashboards
