UPGRADING TO LOTUS NOTES 6 AND LOTUS DOMINO 6

Increased UniqueNameKey (UNK) table size
The Domino 6 Directory template includes a number of new field names that increased the size of the UniqueNameKey (UNK) table. By default, databases are limited to 64K of item names. Domino 5 and Domino 6 databases can exceed this limit if you select the "Allow more fields in database" option in the NAMES.NSF database. Domino 4.6 databases do not support this option. To replicate the Domino 6 Domino Directory to Domino 4.6 servers, upgrade those servers to Domino 4.6.7a. If you replicate the directory to a release prior to 4.6.7a, you receive the error "Cannot store document; database has too many unique field names," then replication ends.
