If you back up an SSISDB from a server running build 275 and restore it to a server running build 260, the catalog will enter a "Recovery Pending" state. The only fix is to either upgrade the target server to build 275 or use the catalog.check_schema_version stored procedure to force a compatibility check (which rarely works cleanly).

A sysadmin applies SQL Server CU14 (which updates SSIS to a new build) and then rolls back due to performance issues. The rollback does not properly revert the SSISDB schema. The SSISDB catalog now expects the newer 275+ build, but the ISServerExec.exe is an older version.

The most frequent trigger for SSIS 275 alerts is version drift between development workstations and production servers.

| Environment | Typical SSIS Version | Build Number Example | | :--- | :--- | :--- | | Developer PC (VS 2019) | SQL Server 2019 | 15.0.2000.275 | | On-Prem Server | SQL Server 2017 | 14.0.2020.295 | | Result | Mismatch | SSIS 275 error |

Once you’ve recovered from the SSIS 275 headache, it’s time to implement policies to ensure it never happens again.

If you see the SSIS 275 error in your SSISDB deployment logs, follow this rigorous troubleshooting checklist.
