The migration of the information systems of UkrSibbank BNP Paribas Group to the new version of the EMC Documentum platform has been completed successfully.
The following information systems were migrated from version 6.0 to 6.6:
- Archive of regulatory and reference documents
- Unified archive of the clients’ banking history files archive with SAP integration
- Application processing system for branches facilities renovations
The following tasks were performed: transition to Documentum 6.6, transition to the new database server Oracle 11G, introduction of Captiva 6.0/6.5, introduction of the x64 version of Application Server. 22 servers were involved in the migration (content, applications, indexing, databases, Captiva). The migration scenario allowed to perform the migration without interruption of customer service.
As a result, the stability of the system could be increased, the rules of high availability have been confirmed, the productivity was increased by 10 to 350 times (for different operations).
As part of the project, stress tests were performed. The purpose was to find and eliminate the «bottle necks» of the system and to confirm the standards of performance at maximum load (up to 6000 concurrent users with read-write requests).
