MOS Note:884522.1 - New preupgrd.sql available

By Mike Dietrich-Oracle on Dec 08, 2015

Whenever you attempt to upgrade an Oracle database to Oracle Database 12.1.0.2 please get themost recent version of preupgrd.sql, the preupgrade check script, (including theutluppkg.sql package) from MOS Note:884522.1 first.

The new version has many improvements over the previous one - and it is more than 2 years "younger" then the one you'll get with a standard installation of Oracle Database 12.1.0.2. It will give you also good advice when you are planning a migration.
