Comparison Table
Deloitte
enterprise_vendorBig Four consultancy with dedicated application modernization and cloud migration practices.
Migration factory delivery combines readiness work with governed wave planning and interface execution to control cutover sequencing.
Deloitte fits teams that need end-to-end migration orchestration, starting from application inventory building and migration readiness assessment to target-state architecture and landing zone setup. Delivery execution emphasizes dependency mapping and wave planning, which helps teams coordinate rehost and replatform streams without losing track of downstream integrations. The service typically includes extensive API and interface work for both application and database migration, which supports integration testing and controlled cutovers. When migration scope spans multiple business capabilities, Deloitte can align the target application stack to business capability mapping and migration factory throughput.
A tradeoff appears in change-management overhead, because Deloitte-style governance and reporting can slow decisions when a team needs quick, small-scope experiments. Deloitte works best when the migration has clear business owners, measurable success criteria, and enough lead time for source-code and compatibility assessments to shape rehost versus refactor choices. It also fits programs where parallel run, user acceptance testing coordination, and rollback rehearsal are required for regulated or high-availability environments.
- +Strong migration readiness and rationalization drive better target choices
- +Governed wave planning reduces cross-app cutover coordination risk
- +Deep integration work for API and system interfaces supports testing
- +Dependency mapping improves ordering of rehost and replatform streams
- –Heavier governance can slow decisions for small or exploratory migrations
- –Execution depends on disciplined input data and stakeholder availability
- –Some teams need internal integration engineers for sustained interface tuning
- –Parallel run planning adds calendar overhead to the migration schedule

Best for: Fits when large enterprises need governed migration orchestration across many dependencies.
Cognizant
enterprise_vendorIT services firm delivering cloud application migration and modernization programs.
Factory-style migration execution with structured cutover and rollback planning across multi-wave dependency graphs.
Cognizant fits organizations running migration at portfolio scale where dependency mapping, landing zone readiness, and repeatable factory execution reduce schedule drift across waves. Teams receive structured planning inputs such as migration readiness assessment, target-state architecture guidance, and cutover and rollback plan templates that align technical teams and business owners. The engagement model also emphasizes integration testing discipline for cross-application interfaces and user flows, which matters when the dependency graph is dense. Cognizant’s integration depth shows up most clearly when migration spans application and data synchronization work rather than application changes alone.
A tradeoff appears in how execution governance can add process overhead for teams that want lightweight migration spikes without standardized cutover controls. Cognizant fits best when a program needs both portfolio decisions and controlled execution, such as multi-wave migrations with parallel run requirements and structured validation checkpoints. Smaller migrations with only a few apps may find the delivery structure more than the project needs, especially when there is no appetite for cross-team dependency work.
- +Strong wave planning and cutover governance across complex dependencies
- +Practical integration testing support for application and interface changes
- +Repeatable engineering standards for mixed rehost and replatform targets
- +Structured readiness assessments that guide technical and sequencing decisions
- –Standard governance can slow teams that need fast, lightweight spikes
- –Refactor-heavy programs require clear scope and engineering ownership
- –Data synchronization work increases coordination needs across teams
- –API compatibility efforts may need additional internal integration engineering

How to Choose the Right Application Migration
We separate options by how much real control they give during application migration, not by marketing promises. The biggest divider is usually API automation, then how well each tool handles dependency-aware sequencing and rollback behavior.
API automation surface for migrations
Why it matters
For application migration, teams need API automation surface to drive repeatable runs and integrate with change management. Better automation reduces manual steps during cutovers and reduces operator error.
How to check
On the demo, ask for an API-driven migration run: create a job from a request, start it, and fetch status programmatically. Check whether common workflow actions are exposed (create plan/run, monitor steps, and retrieve logs/artifacts).
Dependency-aware execution order
Why it matters
Dependency-aware execution order prevents breaks from libraries, shared services, or upstream apps. It matters when you migrate in waves and need predictable sequencing.
How to check
Provide a small sample app set with at least one dependency chain. Ask how the tool computes order and how it shows the chosen sequence before execution.
Data model and schema mapping support
Why it matters
Application migration often fails when data model and schema mapping are unclear. Strong support helps you validate assumptions and avoid silent mismatches during move and verification.
How to check
Ask the team to show how they map source-to-target schema (fields, types, constraints) and what validation reports they produce. If database artifacts are included, review how they preview generated changes before applying them.
Config and environment provisioning controls
Why it matters
Config and environment provisioning controls keep apps consistent across dev, test, and target environments. This reduces drift during migration waves and supports controlled rollout.
How to check
Ask for a demo of how environment settings are captured and applied. Request evidence of what’s configurable (endpoints, credentials references, feature toggles) and whether the tool produces an auditable configuration change record.
Audit logs and migration observability
Why it matters
Audit logs and migration observability make it possible to see what changed, when it changed, and by which run. That visibility is critical for fast diagnosis after a failed step.
How to check
During the demo, trigger a failed run (or a controlled error) and inspect the resulting run timeline. Ask what is recorded: inputs, step outcomes, and links to logs for troubleshooting.
Rollback and recovery workflow options
Why it matters
Rollback and recovery workflow options determine how safely you can correct mistakes mid-migration. In application migration, the recovery path matters as much as the happy path.
How to check
Ask how the tool handles rollback for a step or whole run. Review whether it supports a defined re-run after rollback and what artifacts it keeps or restores.
Red flags
- Migration steps are only clickable in the UI with no usable API-driven workflow
- The tool shows an execution order without explaining dependency reasoning
- Rollback is described as manual work without preserved artifacts or run history
Fit by situation
- If we must run migrations repeatedly across teams and environments, prioritize API automation surface.
- If we’re migrating many interconnected apps in waves, prioritize dependency-aware execution order.
- If rollback and auditability are critical during change windows, prioritize rollback and recovery workflow options.
