If you plan to migrate the domain configuration repository on IBM DB2 or Microsoft SQL Server to a different database during upgrade, you cannot upgrade in silent mode in certain situations.
You cannot upgrade in silent mode in the following situations:
The domain configuration repository is on IBM DB2 and you migrate the repository from a multipartition database to a single partition database.
The domain configuration repository is on Microsoft SQL Server and you migrate the repository from a database in a custom schema to a database in the default schema.
Workaround:
On Windows, upgrade the Informatica domain in graphical mode.
On UNIX, upgrade the Informatica domain in console mode.
