Using VSS 4.0a and 5.0 with VSS 6.0

See Also

VSS 6.0 has a new database format. If you upgrade to this new format, VSS 4.0a, VSS 5.0, Macintosh, and UNIX 4.0/5.0 users will not be able to access the database until they upgrade.

The new database format must be enabled for faster database performance and label promotion.
