Identity migration and AI agents: are your controls ready for the move?

TL;DR: Identity migration is no longer a simple platform swap, because legacy authentication, standing privilege, fragmented policies, and emerging AI-agent access all have to be reconciled at once, according to Newcore. The real risk is copying old identity debt into a new stack, while access review assumptions and lifecycle controls fail to keep pace with machine-speed identity behaviour.

NHIMG editorial — based on content published by Newcore: identity migration and the need for a stronger identity foundation

By the numbers:

• The ratio of non-human to human identities now reaches 25x to 50x in modern enterprises.
• Only 5.7% of organisations have full visibility into their service accounts.

Questions worth separating out

Q: What breaks when identity migrations focus only on platform replacement?

A: Teams usually preserve the same weak lifecycle processes inside a newer stack.

Q: Why do compromised identities remain such a persistent risk in identity security programs?

A: Compromised identities are persistent because access often outlives the original approval, especially for service accounts, API keys, and delegated privileges.

Q: How do security teams know modernization is actually reducing risk?

A: They should look for fewer standing privileged accounts, higher MFA coverage, shorter patching cycles, and clearer inventory of human and non-human access.

Practitioner guidance

• Map every identity dependency before cutover Build a complete inventory of identity providers, applications, groups, policies, authentication methods, and delegated access paths so the migration team can see where changes will propagate.
• Remove standing privilege as a migration workstream Use the transition window to rightsize roles, eliminate excess administrative access, and convert sensitive operations to just-in-time approval where possible.
• Treat AI agent access as governed delegation Assign explicit ownership for each agent, define its permitted actions, and require the same review discipline you would apply to other non-human identities.

• The way Newcore says AI agents fit into the transition model for humans and machines.
• The practical rollout approach for reducing access risk without disrupting business continuity.
• The platform-specific mechanics behind authentication and authorization changes during modernization.
