This article explains when the metadata structure of Netezza is not updated after migration.
This procedure only applies to the Profiling perspective when migrating Netezza connections from 5.5.1, 5.6.0, and below to more recent versions of the Studio. For migration between other versions of the Studio, the problem does not exist.
After migrating a Netezza connection from 5.5.1 and below or 5.6.0 and below, the metadata structure will be Catalog > Table > Columns. There will be no Schema between Catalog and Tables.
This problem does not exist in the 5.5.2, 5.6.1, 6.0.0, and above releases. The metadata structure of Netezza connections will display correctly after migration, that is, you will have Catalog > Schema > Table > Columns.
This problem of the missing Schema directory in the metadata structure of a migrated Netezza connection is only a display issue. The connection will continue to work normally in the Studio.
