The correct answer is A. There was a database schema upgrade failure during the installation. The vCenter 5.x to 6.0 upgrade failed because the database schema migration was initiated but did not complete successfully, leaving the schema at an incompatible intermediate version.
Question
A failed upgrade from vCenter Server version 5.x to version 6.0 produces the following error:
[00800 error 'Default'] Database version id '600' is incompatible with this release of VirtualCenter. What is the cause of the upgrade failure?
Options
- AThere was a database schema upgrade failure during the installation.
- BThe VMWAREVCMSDS service was upgraded before the vCenter Server service.
- CThe VMware Directory Service database failed during the installation.
- DThere was an incompatible ODBC driver version for the database.

Why each option
The vCenter 5.x to 6.0 upgrade failed because the database schema migration was initiated but did not complete successfully, leaving the schema at an incompatible intermediate version.
The error message referencing 'Database version id 600' confirms the installer attempted to migrate the vCenter database schema to the version 6.0 format but failed mid-process, resulting in a schema state that is incompatible with both the old and new vCenter Server binaries.
VMWAREVCMSDS is the VMware Directory Service and is unrelated to the core vCenter SQL or Oracle database schema version - its upgrade order would not generate a database version ID mismatch.
VMware Directory Service maintains its own internal VMDIR database, which is separate from the vCenter inventory database referenced by the version ID '600' error.
An incompatible ODBC driver would cause a connection-level failure or SQL execution error, not a version ID incompatibility message produced during schema migration.
