Move to cloud without the migration debt that follows
Most enterprise cloud migrations arrive in production carrying technical debt, ungoverned data, and manual runbooks that replace the old on-premises manual runbooks. BCS delivers Symphony-orchestrated migrations where cutover sequences, rollback procedures, and post-migration operations are automated before the first workload moves.
Which migration path fits the landscape?
Enterprise cloud migration has three distinct starting points, and the approach that works for a greenfield workload breaks a legacy ERP environment. BCS maps each workload to the correct migration pattern before a single VM moves.
The failure pattern is consistent: programmes that treat all workloads as lift-and-shift candidates accumulate technical debt faster than the migration creates value. Symphony-orchestrated migration executes the correct pattern per workload, automating cutover sequences and post-migration runbooks so operations teams are not inheriting manual processes disguised as cloud infrastructure.
Six failure modes BCS is built to prevent
Cloud migration failure is rarely a technology problem. The workloads that arrive in production broken — carrying manual runbooks, ungoverned data, and stranded dependencies — failed in planning, not execution.
Lift-and-shift applied to workloads that need re-architecture
Treating every workload as a simple VM move creates cloud infrastructure that costs more than on-premises and performs worse. Dependencies, licensing models, and data gravity require per-workload migration pattern decisions.
Manual cutover runbooks that fail under time pressure
Runbooks written for a planned 6-hour cutover window become 18-hour incidents when a dependency is missed at hour four. Symphony-automated cutover sequences execute deterministically and roll back cleanly when a pre-defined gate fails.
Data integrity not validated before source systems go dark
Migrations that declare success on workload completion miss the data quality failures discovered weeks later. deKorvai validates record counts, referential integrity, and business-critical field completeness before the source is decommissioned.
Identity and access not migrated in step with workloads
Application permissions, service accounts, and privileged access granted during migration rarely get cleaned up. Anugal governs cloud identity from day one, ensuring access granted for migration activities does not persist into steady-state operations.
Stranded hybrid state treated as a temporary phase
Programmes that tolerate an extended hybrid operating model accumulate costs on both sides of the boundary. The data gravity problem grows with every month of parallel running, making the final decommission progressively harder to execute.
Post-migration operations inherited as a manual problem
The operations team that inherits a migrated environment without automation is managing cloud infrastructure with on-premises methods. The productivity gain projected in the business case does not materialise if post-migration ops are not automated at handover.
What cloud migration delivers
Data center costs eliminated on schedule
Workload migration executed against a defined decommission plan means lease and hardware costs end when the programme says they will, not months later when stranded dependencies are finally resolved.
Data integrity confirmed before source decommission
deKorvai validation runs before every source system is taken offline, giving operations and compliance teams confidence that migrated data matches the expected record counts, field values, and referential structure.
Cutover windows measured in hours, not days
Symphony-automated cutover sequences execute dependency chains, health checks, and rollback triggers deterministically. Planned 6-hour windows complete in under 4 hours on average across comparable engagements.
Post-migration operations automated at handover
Operations teams inherit Symphony-managed runbooks, not spreadsheets. Monitoring, scaling triggers, patch cycles, and incident response sequences are automated before the first production ticket arrives.
Cloud spend visible and governed from day one
Cost allocation tagging, budget alerts, and resource lifecycle policies are configured as part of the migration, not retrofitted after the first surprise billing cycle.
Identity access cleaned up, not inherited
Migration-phase service accounts, break-glass access, and emergency permissions are revoked at cutover. Anugal governs the cloud identity estate from steady-state day one, not from the date someone notices the cleanup is overdue.
How BCS delivers cloud migration
Five phases that take each workload from discovery to automated steady-state operations, with Symphony orchestration embedded from assessment through to handover rather than bolted on after go-live.
Discovery and Workload Classification
Automated discovery tools map every workload, dependency, and data flow across the current estate. Each workload is classified: lift-and-shift, re-platform, refactor, retire, or retain. Migration pattern decisions are recorded with business justification before any execution begins.
Landing Zone and Governance Foundation
Target cloud environment built to the provider's Well-Architected Framework — AWS, Azure, or GCP. Network topology, identity boundaries, cost allocation tagging, and security baselines are established before workloads arrive. Anugal governs cloud identity from this stage forward.
Wave Planning and Symphony Automation Build
Workloads grouped into migration waves by dependency order and business criticality. Symphony cutover sequences, rollback triggers, and health check gates are built and tested in the target environment before any production data moves. Automation is validated, not assumed.
Wave Execution with deKorvai Validation
Each wave migrates with Symphony-automated cutover and deKorvai data validation checkpoints. Record counts, referential integrity, and critical field completeness are verified before each source system is marked for decommission. Failed validation gates halt the wave, not the programme.
Decommission and Automated Steady-State Handover
Source systems formally retired on the programme schedule. Operations teams handed Symphony-managed runbooks covering monitoring, scaling, patching, and incident response. The programme ends when operations are automated, not when the last workload has been moved.
What BCS delivers on a cloud migration engagement
Nine migration capabilities covering the full scope from workload discovery to automated post-migration operations, executed by specialists who have completed enterprise-scale migrations across AWS, Azure, and GCP.
Workload Discovery and Dependency Mapping
Automated scan of the current estate producing a complete inventory of workloads, inter-application dependencies, data flows, and integration endpoints before migration planning begins.
Migration Pattern Assessment
Per-workload classification into lift-and-shift, re-platform, refactor, retire, or retain, with documented business and technical justification for each pattern selection and the cost implications of each choice.
Cloud Landing Zone Design
Target environment built to AWS Well-Architected, Azure Landing Zone, or GCP Blueprint standards — network segmentation, identity boundaries, logging infrastructure, and cost allocation tagging established before workloads arrive.
Containerisation and Kubernetes Migration
Application containerisation using Docker, orchestration configuration with Kubernetes or managed equivalents (EKS, AKS, GKE), and Symphony-managed deployment pipelines with automated health checks and self-healing configuration.
Symphony Cutover Automation
Migration cutover sequences built as Symphony-orchestrated workflows: dependency order enforcement, automated health check gates, rollback trigger logic, and post-cutover validation steps — all executed without manual intervention.
deKorvai Data Validation
Pre-decommission validation of migrated datasets: record count reconciliation, referential integrity checks, critical field completeness, and business-rule validation against source system snapshots before source systems go dark.
Cloud Identity Governance
Anugal governs cloud identity from landing zone build through migration execution and into steady state — migration-phase service accounts, break-glass access, and emergency permissions revoked at cutover, not carried forward.
SAP and Enterprise Application Migration
Specialist migration of SAP landscapes — BASIS team-led infrastructure migration for SAP S/4HANA, ECC, and BTP workloads to hyperscaler targets, coordinated with any concurrent S/4HANA transformation programme.
Post-Migration Operations Handover
Formal handover package including Symphony-managed monitoring runbooks, auto-scaling policies, patch cycle automation, incident response playbooks, and cost optimisation recommendations — ready for the operations team before the programme closes.
What other cloud migration partners cannot offer
Every BCS cloud migration engagement runs on Symphony, deKorvai, and Anugal. These are not add-ons quoted separately — they are the execution layer that makes cutover automation, data validation, and identity governance possible from day one.
Symphony
Symphony orchestrates migration cutover sequences as automated workflows — dependency ordering, health check gates, rollback triggers, and post-cutover validation steps execute without manual intervention. Wave execution is deterministic: each step completes before the next begins, and a failed gate halts the sequence cleanly rather than leaving infrastructure in a partially migrated state.
- Automated cutover sequences with pre-tested rollback
- Wave dependency ordering and health check gates
- Post-migration monitoring and auto-scaling runbooks
- SAP BASIS migration orchestration for S/4HANA landscapes
deKorvai
deKorvai validates migrated data against source system snapshots before any source is decommissioned. Record count reconciliation, referential integrity checks, and critical field completeness run as automated checkpoints at each wave boundary. Data quality failures surface before the cutover completes, not weeks later when a business process discovers missing records in the target environment.
- Pre-decommission record count and integrity validation
- Business-rule validation against source system snapshot
- Data scrambling for non-production cloud environments
- ETL pipeline validation for cloud data platform migrations
Anugal
Anugal governs cloud identity from landing zone build through wave execution and into steady-state operations. Migration programmes accumulate service accounts, emergency access grants, and privileged roles that rarely get cleaned up when the programme closes. Anugal tracks every access grant made during migration and enforces revocation at cutover, so steady-state cloud operations inherit a governed identity estate, not a migration-phase access sprawl.
- Cloud IAM role governance from landing zone build
- Migration-phase access revocation at cutover
- Continuous access monitoring for cloud-native services
- Compliance reporting for cloud identity posture
What makes BCS different from every other cloud migration partner
Most cloud migration partners deliver workloads to the target environment and hand over a document. BCS delivers workloads with automated operations, validated data, and governed identities — because a migration is not complete until the programme team can leave without the operations breaking.
Automation built during migration, not after
Symphony cutover sequences and post-migration runbooks are built and tested in the target environment during the programme. Operations teams do not inherit manual processes disguised as cloud infrastructure.
Data validated before the source goes dark
deKorvai validation checkpoints run before each source system is decommissioned, not after. Business teams confirm data integrity is intact before, not after, the rollback window closes.
Identity governed from landing zone, not cleaned up later
Anugal governs cloud identity from the first day of landing zone build. Migration-phase access is revoked at cutover on schedule, not when a compliance review finds it 18 months later.
SAP and enterprise application specialists on the team
Migrations involving SAP S/4HANA, ECC, or BTP workloads are handled by BCS BASIS specialists who understand SAP's cloud infrastructure requirements — not generalist cloud engineers working from documentation.
Per-workload pattern decisions, not a single migration approach
Discovery and classification determine the migration pattern for each workload. Applying lift-and-shift to applications that need re-platforming creates cloud debt that costs more to fix than the original migration.
Decommission on schedule, not when the last dependency is resolved
Dependency mapping completed in discovery means decommission planning is not revised at every wave. Source systems retire when the programme schedule says, not when the team finally tracks down the last undocumented integration.
