COMADMIN_E_MIG_SCHEMANOTFOUND
COMADMIN_E_MIG_SCHEMANOTFOUND is the failure HRESULT 0x80110481 (signed decimal -2146368383, unsigned decimal 2148598913). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x0481.
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 the result 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 this result, record catalog version, schema identifiers, installation/servicing state, and whether migration resources match the OS build.
Evidence to collect before repair
- Evidence for it should include source and target OS/catalog versions, captured before a repair changes state.
- Collect schema identifiers and servicing state when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- The result investigation needs backup provenance and restore sequence so the exact failing boundary remains reconstructable.
- preserve available application exports and component installers; it anchors the failure to the real administration object.
Diagnostic sequence
- At the boundary, preserve the original catalog backup.
- The next this result diagnostic action is to verify a Microsoft-supported upgrade sequence.
- To isolate this result, repair COM+ servicing resources when schemas are missing.
- prefer export/redeployment for applications when direct migration is unsupported.
- At the 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.
