In case you’ve never encountered SSIS Catalog Error 27150, the error message reads:

The version of the project has changed since the instance of the execution has been created. Create a new execution instance and try again.

A customer recently encountered this error.
So… what happened?

Short Answer

The version of a project changed during the execution of an SSIS package that is part of that project because the project was re-deployed while the SSIS package was executing.

In this particular case, the SSIS package execution takes about 30 seconds and runs once per hour.

Talk about timing.
