Moving to 12​.1SP4 from Previous Releases - *12​.1​.SP4*

Mixing 12.1SP4 with prior software versions on the same databases is not appropriate; such usage can cause database inconsistencies. It is therefore strongly recommended, though not mandatory, to upgrade the project to 12.1SP4 level, by running the optional upgrade provided with the 12.1SP4 installation. By applying this upgrade the databases are protected from being updated by any version prior to 12.1.SP4.

The upgrade level denoted 12010401 is an optional upgrade provided by release of 12.1 SP4 and contains one upgrade item only:

Item: 93792, General database changes.
