TL;DR: IGA migrations often stall because application onboarding becomes the hidden critical path, with each system introducing its own account model, entitlement structure, and remediation workflow, according to Redblock. Starting application readiness before platform selection turns migration sequencing into a governance problem rather than a tooling problem.
Editorial analysis by NHI Mgmt Group, based on content published by Redblock: “Why IGA Migration Should Start Before You Choose the IGA”.
Key questions
Q: What breaks when IGA migrations start with platform selection instead of application readiness?
A: The migration loses visibility into the systems that actually enforce access.
Q: Why does an IGA migration create more risk than a normal application migration?
A: IGA platforms sit inside access reviews, provisioning, lifecycle changes, and compliance reporting, so a migration affects both operations and proof.
Q: What do identity teams get wrong about IGA migration sequencing?
A: They often treat application onboarding as a downstream task after the platform decision is made.
Practitioner guidance
- Map application readiness before platform commitment Inventory account models, entitlement structures, workflow exceptions, and connector constraints before locking the IGA architecture.
- Split migration into two workstreams Run IGA selection and application readiness in parallel so discovery of hard-to-govern applications happens before timelines are fixed.
- Validate enforcement inside each application Require proof that access changes, deprovisioning, and remediation actions actually changed the downstream application state.
Bottom line: IGA migrations stall when application onboarding is left until after platform selection, because the hardest work sits in the estate, not the software.

Application readiness is the real migration control point. The article shows that IGA programmes fail less because the governance model is wrong and more because the application estate is not ready to absorb change. That is a sequencing failure, not a feature gap. When onboarding and remediation are deferred, the migration becomes a forced compromise between coverage and schedule. Practitioners should treat application readiness as the primary determinant of governance effectiveness.
A few things that frame the scale:
- 74% of organizations report identity-related breaches, and privileged access is a leading cause of lateral movement.
A question worth separating out:
Q: When should organisations start application readiness in an IGA programme?
A: Application readiness should start before the platform decision is finalised, or at minimum in parallel with it. That timing exposes connector gaps, data quality problems, and execution constraints early enough to influence architecture and prioritisation instead of forcing late compromises.
