Customer
"The entire upgrade project of our 300 Oracle databases at Swiss Mobiliar was completed in time without issues. When we encountered issues, we fixed them before going live. Features such as Oracle In-Memory added a lot of performance boost to some of our applications. Especially the Oracle Upgrade Reference Program was a great help and added a lot of value to our project's progress. We are very happy and satisfied with the upgrade process and the reliability and performance of Oracle Database 12c". Paolo Kreth, Group Manager Databases, Mobiliar
