TPMAPI_E_INVALID_MIGRATION_AUTHORIZATION_BLOB
TPMAPI_E_INVALID_MIGRATION_AUTHORIZATION_BLOB is a Windows TPM API result. It indicates that supplied migration authorization data is malformed, incompatible, or not valid for the requested migration operation.
What to check for TPMAPI_E_INVALID_MIGRATION_AUTHORIZATION_BLOB
- Verify that the authorization blob was created for the same migration workflow and target object.
- Check blob integrity and ensure it was not truncated, transformed, or decoded as text.
- Recreate migration authorization data rather than attempting to repair an unknown blob.

Diagnostic interpretation
This result has the HRESULT value 0x80290112. AllStat records the condition as “The requested supplied data does not appear to be a valid migration authorization blob.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the tpmapi / migration / authorization / blob operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original tpmapi / migration / authorization / blob condition.
