The following document describes the procedure used to move the EGATE Production database environment from the current Power 4 architecture to the Power5/6/7 architecture on the p590's with the Production Disaster Recovery provisions in place.

  1. The first phase of this process is to shutdown the EGATE database environment on the current Power 4 production platform.

  2. The second phase is to acquire the production resources on the Power5/6/7 systems.

  3. The third phase is to start the production EGATE database environment on the Power5/6/7 systems.

  4. The last phase is to verify and implement monitoring.

Phase 1

- Shutdown the EGATE database environment on the production platform.
