AWS IAM Identity Center Now Keeps Your Users When Switching Identity Sources
AWS IAM Identity Center now preserves your workforce identities, groups, and access assignments when you switch from Active Directory to external providers like Okta or Microsoft Entra ID—no more recreating everything from scratch. This feature works across all AWS Regions where IAM Identity Center is available, keeping your user IDs intact so existing policies and access continue working seamlessly.
