  3. Scope of the upgrade project • The upgrade of the SAP ISU system from version 4.6.4. to ERP6.0 is a technical upgrade only • No new functionality will be switched on for the upgrade project • A separate (Development & Test) upgrade landscape will co-exist during the life of the project • Production system changes are minimised during the upgrade project as a result of a system freeze, to support the current design. • No change to XML messaging • No change to Hub systems See-beyond or SAP XI

  6. Inter Participant Testing • As agreed with Gemserv, IPT is not a requirement for this project • Informal message testing is currently being carried out between the ESB IT competency centres for ESB Networks & ESB Customer Supply • The upgrade project will be upgrading the Market system test environment on the 29th January 2009 • There is a Market Testing Window available between 9th to 27th February • ESB Networks would welcome other Market Participants to re-test market messaging

  7. Cutover Planning • The cutover dates will be Friday 10th to Monday 13th April • The step by step cutover plan to cater for the SAP ISU upgrade is currently being developed with timing estimates. • There will be 2 Dress rehearsals to validate and tweak the technical cutover plan. • During cutover, market messages send from Market Participants to Networks will queue in the HUB until the system is restored • Arrangements for data aggregation runs and meter reading processing are currently being planned • Contingency arrangements will be put in place over cutover to revert back to the previous version, should we experience problems.
