After upgrading eDiscovery Bundle to 3.7 Service Pack 2 all Legal Review Indexer actions fail for existing matters

SYMPTOMS

After upgrading eDiscovery Bundle from version 3.4 or earlier to 3.7 sp2, all Legal Review Indexer actions fail for matters created before the upgrade. Legal Review Indexer actions succeed for new Matters, created natively in eDiscovery Bundle 3.7 sp2. The upgrade was executed on a ZyLAB Cluster where the eDiscoveryProcessing Service runs on a dedicated node (eDiscovery Node), isolated from the Processing Service. By looking at the Date Modified, you notice that some DLL files (ZyLAB.EDiscovery.Common.Contracts.Portable.dll, ZyLAB.EDiscovery.Common.Processing.dll, ZyLAB.EDiscovery.Indexers.AddToLegalReview.dll, ...) have been updated in the "Shared\LP_MATTER_ID\Assemblies\Performers" folder for each matter, but no XML file has been updated. Depending on the deployment, Legal Review Indexer actions may fail with either one of the following errors. 1. Error(s) adding document(s) 2. Legal Review Indexer couldn't add documents to index after 10 attempts. The last exception message was: There was no endpoint listening at http:// HOSTNAME_HERE /LegalReviewWeb/Services/StandAlone/ProcessingFacade.svc that could accept the message

CAUSE

eDiscovery Bundle 3.7 sp2 installer modifies configuration for existing matters during upgrade of the Processing Service. In case the Processing Service does not run on the same cluster node as eDiscoveryProcessing Service, configuration for existing matters may not be updated.

RESOLUTION

Manually update the ZyLAB.EDiscovery.Indexers.AddToLegalReview.dll.xml configuration files for existing matters. You can do this by either modifying or replacing the "Assemblies\Performers\ZyLAB.EDiscovery.Indexers.AddToLegalReview.dll.xml" configuration files for each existing matter in the Shared location.
