Deduplicator actions fail and "Invalid column name 'DuplicateHashValue'" error is logged after eDiscovery Bundle upgrade from version 3.4 to 3.6 with Best Practices.

SYMPTOMS

Deduplicator actions fail and "An error occurred while updating the entries. See the inner exception for details. ---> Invalid column name 'DuplicateHashValue'." error is logged after upgrading from eDiscovery Bundle version 3.4 to 3.6 with Best Practices.

CAUSE

The 'ZyLABDeduplicator' database schema hasn't been updated.

RESOLUTION

The eDiscovery Bundle Best Practices 3.6 installation guide steps that apply to your deployment need to be followed in full. Please note that when you run the "04_Create_ZyLABDeduplicatorDatabase.sql" script, the old 'ZyLABDeduplicator' database will be dropped and a new one, compatible with 3.6, will be created. You can backup the old database to save the data, but you won't be able to use the old 'ZyLABDeduplicator' schema on 3.6.

APPLIES TO

3.6
