The main goal of this project is to adapt & migrate the existing platform from an on-premise Linux environment to AWS.

That means the team adapted the system source code in order to make the components cloud compliant (but still maintain support for on-premise architecture).

The team also prepared and ran a protocol to transfer large volumes of data and metadata and to automate the analysis of the differences between the old and new instances.
