Homegrown CIAM migration in health tech: what changes for teams?

TL;DR: Health tech teams moving from homegrown CIAM to a vendor platform can preserve passwords with standard hashing, migrate users in bulk or incrementally, and add enterprise features such as MFA, SSO, SCIM, and audit logs with less custom code, according to Frontegg. The security issue is not just migration speed but whether identity has become too fragile to govern safely in-house.

Questions worth separating out

Q: How should health tech teams migrate from homegrown CIAM without breaking access?

A: Start by separating credential continuity from access governance.

Q: When does a homegrown CIAM system become too risky to maintain?

A: It becomes too risky when the team is spending more time preserving login flows than improving the product, or when authentication, audit, and provisioning changes routinely require bespoke fixes.

Q: What do teams get wrong about CIAM migration projects?

A: They often focus on whether users can sign in after the cutover and ignore whether roles, audit trails, and support workflows still match the old system.

Practitioner guidance

• Map identity control debt before migration Inventory which CIAM functions are now being carried by custom code, including password handling, SSO, MFA, audit logging, and account hierarchy logic.
• Validate password hash compatibility early Confirm which hashing algorithms are currently in use and test whether the destination platform can preserve them without forced resets.
• Treat SCIM and audit logs as governance controls Use SCIM to standardise provisioning and deprovisioning, and verify that audit logs capture the identity events compliance teams will need later.
