VOB schema versions

Each VOB has a database schema version that denotes the format of the VOB database and determines the types of data and metadata that the VOB can store.

Versions of Rational® ClearCase® earlier than 7.0 support schema version 53 and schema version 54. Rational ClearCase V7.0 supports only schema version 54. Schema version 54 is required when using Rational ClearCase in a Microsoft® Active Directory environment. Schema version 54 also provides support for VOB database files larger than 2 GB.

Reformatting a VOB to schema version 54
When you upgrade a VOB server host to Rational ClearCase version 7.0, you must reformat all VOBs on that host to schema version 54.
