Moving from v7.x to v8.x is not easy. You need Courion expertise and skills to upgrade and migrate the data

Courion AAS is by no accounts scalable. Though it is possible to run multiple web-application servers in parallel, there are issues that prevent true high availability. For example, links between web and application servers must be hardcoded in a 1:1 relationship, meaning that the web and app tiers are not fully distributed and balanced. This would also require custom development to include "health check" workflows which would validate the functionality of application servers.
