Upgrade and migration of SAP BW 7.3 on Oracle to SAP BW 7.5 on SAP HANA was successfully done!11/08/2017
In this PoC project we performed upgrade and migration of SAP BW 7.3 on Oracle to SAP BW 7.5 on SAP HANA. Project goals were to verify seamless integration of SAP HANA DB into current landscape and operations, performance improvements of SAP BW, verification of expected costs for AWS operations, IT operations and Go-Live project labour.
SAP HANA was installed in scale-out scenario across 3 servers due to the size of BW (7TB compressed with ACO) and AWS server size limitations. During PoC SAP HANA installation was fully automated with Ansible and thus reducing future deployment costs. During PoC we were solving bug with SAP support for almost one month but as we used On-Demand AWS instances and started systems only when necessary PoC budget was not exceeded despite this unplanned PoC duration extension.“
