Comparison Table
Capgemini
enterprise_vendorEuropean-origin IT services leader running cloud and application platform migration programs.
A migration factory operating rhythm links assessment artifacts to wave-level execution, cutover readiness, and reconciliation checkpoints across teams.
Capgemini typically starts with platform assessment outputs like current-state inventory, dependency mapping, and target-state architecture alignment so teams can size waves and define technical constraints early. Delivery then follows migration strategy decisions such as lift-and-shift for low-risk components and refactoring for integration-heavy services, with a coordinated coexistence period and cutover plan. Data migration work includes extraction and transformation plus reconciliation reporting to detect mismatches before business signoff.
A tradeoff appears in the coordination overhead that comes with large program governance and parallel workstreams, which can slow early momentum on small scope migrations. Capgemini fits best for enterprises migrating many applications with shared integration patterns where automation and controlled rollout matter more than rapid single-app changes.
- +Migration factory delivery model supports repeatable wave execution
- +Dependency mapping and integration planning reduce late cutover surprises
- +Identity and configuration migration work is run as tracked streams
- +Reconciliation reporting improves data validation during migration phases
- –Governance-heavy programs add coordination overhead for narrow migrations
- –Early-stage change requests can impact dependency remapping cycles
- –Complex integration programs demand strong client ownership
- –Architecture alignment workshops require deliberate stakeholder attendance

How to Choose the Right platform migration
Platform migration work turns assessment artifacts into wave-level execution, cutover readiness, and reconciliation checkpoints across apps and teams at Capgemini. Other enterprise delivery models focus on coordinated wave planning tied to dependency mapping, cutover, rollback, and parallel run execution, including IBM Consulting and Accenture. Thoughtworks and Deloitte add engineering- and governance-led execution paths that convert strategy into migration-ready runbooks and traceable decisions across waves. This guide frames provider differences in integration planning, automation surface, and governance depth using the delivery mechanics described for each vendor.
The category commonly spans replatforming, refactoring, and phased coexistence through coordinated migration wave planning, dependency mapping, and cutover rehearsals. Provider approaches diverge on how tightly dependency mapping and reconciliation tie into execution cadence, and how much process overhead appears when the scope shrinks. Capabilities also vary in how migration wave planning links to rollback planning and data validation so changes can be controlled during parallel runs. Capgemini, IBM Consulting, Thoughtworks, Accenture, and Deloitte serve as the main reference points for these tradeoffs across the ten entries.
Platform migration services that coordinate wave planning, cutover, rollback, and reconciliation

Infosys supports API-centered provisioning and environment replication for coexistence periods with wave-based migration execution.
Coexistence design that reduces downtime pressure during parallel runs
Valtech builds migration wave planning around coexistence design to minimize downtime and manage parallel run risk. Publicis Sapient coordinates cutover planning, test cycles, and post-release hypercare across engineering and operations, which affects how quickly stabilization work completes after coordinated releases.
How to choose a platform migration delivery model
The right provider depends on the migration delivery philosophy that fits the enterprise governance and engineering decision pace. Buyers should evaluate whether the provider’s wave mechanics assume centralized decision throughput or distributed team ownership, because this changes schedule stability during target-state architecture choices.
Match governance intensity to the enterprise’s wave decision throughput
Capgemini supports repeatable wave execution using a migration factory delivery model that ties assessment artifacts to cutover readiness and reconciliation checkpoints across teams. IBM Consulting and Deloitte also emphasize wave governance, but Capgemini’s governance-heavy model adds coordination overhead when scope narrows and change requests arrive early.
Pick a dependency-first workflow that also covers rollback and parallel run
IBM Consulting connects dependency mapping to cutover, rollback, and parallel run execution for shared services, which reduces ordering mistakes across hybrid applications. Deloitte and Accenture tie dependency mapping to rollback planning and cutover rehearsal, which matters when the coexistence period requires controlled release orchestration.
Choose engineering-refactoring depth when the target architecture needs runbook-level execution
Thoughtworks converts migration strategy into migration-ready runbooks and operational guardrails that engineering teams use during coordinated cutover and rollback. Accenture and Capgemini support replatforming and refactoring through wave execution rhythms, but Thoughtworks is the clearer fit when the enterprise needs architecture-guided operational guardrails rather than design-only outputs.
Decide whether provisioning and integration validation must be API-centered or script-centered
Infosys emphasizes API-centered provisioning and environment replication for coexistence periods, which shapes how cutover orchestration plugs into enterprise tooling. EPAM Systems provides reusable automation scripts for environment provisioning and interface validation, which suits programs that require high-throughput interface checks.
Validate coexistence mechanics against downtime targets and stabilization timelines

Enterprises managing downtime constraints and parallel run risk during coexistence
Valtech structures migration wave planning around coexistence design to minimize downtime and manage parallel run risk across dependencies and integrations.
Common pitfalls in platform migration sourcing
A frequent failure mode is treating wave governance as an optional program artifact instead of a mechanism that drives cutover sequencing, rollback readiness, and reconciliation checkpoints. Another failure mode is assuming dependency mapping is enough without rehearsal mechanics that validate integration behavior during parallel runs.
Signing up for wave planning deliverables without a rollback and parallel run execution path
IBM Consulting ties dependency mapping to cutover, rollback, and parallel run execution, which keeps shared service migrations from breaking during coexistence. Deloitte and Accenture also connect dependency mapping to cutover rehearsal and rollback planning, which reduces rollback ambiguity during wave transitions.
Underestimating the identity migration ownership and approval latency needed for engineering-led programs
Thoughtworks flags that identity migration decisions require sustained client ownership and fast approvals, which can block engineering runbook delivery. Cognizant also couples wave planning with checkpoint governance, and it expects meaningful client participation across identity and integration workstreams.
Assuming automation depth will stay consistent across workstreams and program team handoffs
Cognizant notes that automation depth varies by migration workstream and tooling choices, which can create uneven execution across wave slices. EPAM Systems and Infosys provide automation-focused approaches using scripts or API-centered provisioning, but buyers should map which workstreams receive automation versus manual coordination.
Choosing a governance-heavy model for narrow migrations and then changing scope during dependency remapping cycles
Capgemini’s governance-heavy programs add coordination overhead for narrow migrations, and early-stage change requests can impact dependency remapping cycles. Accenture also carries dependency mapping depth variation by engagement team and tools used, which affects stability when scope contracts.
