COMADMIN_E_MIG_VERSIONNOTSUPPORTED
COM+ catalog migration: exact meaning of COMADMIN_E_MIG_VERSIONNOTSUPPORTED
The installed COM+ registry database version cannot be migrated by this migration path. Catalog migration reads source-version metadata and rejects it as unsupported.
Windows describes this condition as “This version of the COM+ registry database cannot be migrated”.
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 source OS/catalog version, destination version, backup provenance, and every intermediate upgrade requirement.
Evidence to collect before repair
- Preserve source and target OS/catalog versions; it anchors the failure to the real administration object.
- Evidence should include schema identifiers and servicing state, captured before a repair changes state.
- Collect backup provenance and restore sequence when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record available application exports and component installers.
Diagnostic sequence
- Preserve the original catalog backup.
- verify a Microsoft-supported upgrade sequence.
- The next diagnostic action is to repair COM+ servicing resources when schemas are missing.
- To isolate this result, prefer export/redeployment for applications when direct migration is unsupported.
- Validate applications and activation after migration.
Retry and recovery
Use a supported upgrade sequence or export/redeploy applications through documented package operations.
Difference from nearby COMADMIN results
COMADMIN_E_SESSION concerns live administration compatibility; this value concerns persistent database migration.
Practical administration scenario
An old catalog backup is restored directly onto a much newer server without the required intermediate migration path.
