einue There is currently no built-in support for this scenario. When you change the identity provider and user synchronization runs, the system attempts to match users based on the fields in the IWA_User system table:
IWA_User.ExternalIdIWA_User.ExternalNameIWA_User.UserName
If any of these values match, the corresponding Axon Ivy user identity will be reused and all Axon Ivy - side attributes will be updated accordingly. In many cases, this is sufficient to ensure a smooth transition when switching identity providers.
If no matching attributes are found, I recommend creating a migration job or SQL script to update the IWA_User.ExternalId values for your users. Important: Shut down the Axon Ivy Engine before modifying the ExternalId, then restart the engine once the update is complete.
