COM+ catalog migration: exact meaning of COMADMIN_E_MIG_SCHEMANOTFOUND

The schema version required for COM+ registry-database migration is missing. Migration selects a source schema and cannot locate its transformation metadata in RegDB.

AllStat records this condition as “The schema version to be migrated could not be found in the COM+ registry database”.

Where COMADMIN_E_MIG_SCHEMANOTFOUND occurs

Catalog migration is versioned schema transformation; a database copied from another release is not equivalent to an application package exported through COMAdmin. In the specific case of COMADMIN_E_MIG_SCHEMANOTFOUND, record catalog version, schema identifiers, installation/servicing state, and whether migration resources match the OS build.

Evidence to collect before repair

  • Evidence for COMADMIN_E_MIG_SCHEMANOTFOUND should include source and target OS/catalog versions, captured before a repair changes state.
  • Collect schema identifiers and servicing state when diagnosing COMADMIN_E_MIG_SCHEMANOTFOUND; without it the symbolic HRESULT is underdetermined.
  • The COMADMIN_E_MIG_SCHEMANOTFOUND investigation needs backup provenance and restore sequence so the exact failing boundary remains reconstructable.
  • For COMADMIN_E_MIG_SCHEMANOTFOUND, preserve available application exports and component installers; it anchors the failure to the real administration object.

Diagnostic sequence for COMADMIN_E_MIG_SCHEMANOTFOUND

  • At the COMADMIN_E_MIG_SCHEMANOTFOUND boundary, preserve the original catalog backup.
  • The next COMADMIN_E_MIG_SCHEMANOTFOUND diagnostic action is to verify a Microsoft-supported upgrade sequence.
  • To isolate COMADMIN_E_MIG_SCHEMANOTFOUND, repair COM+ servicing resources when schemas are missing.
  • For COMADMIN_E_MIG_SCHEMANOTFOUND, prefer export/redeployment for applications when direct migration is unsupported.
  • At the COMADMIN_E_MIG_SCHEMANOTFOUND boundary, validate applications and activation after migration.

Difference from nearby COMADMIN results

COMADMIN_E_MIG_VERSIONNOTSUPPORTED means the version is known but unsupported; this value means the needed schema cannot be found.

Retry and recovery

Repair the COM+ installation or use a valid catalog backup and supported migration path.

Practical administration scenario

A partially serviced system has a catalog version marker but lacks the matching migration schema resources.
