The client has a legacy platform that is still heavily used by M&A analysts. This is a C-based system with data stored in legacy Oracle database with stored procedures. The UI is based on legacy .Net and is available as a thick Windows client via Citrix terminal. The C-part of the system is mostly dedicated to ETL-like logic of collecting data form various upstream feeds and sources, doing some basic transformation and dumping that into a staging area of the DB. The transformation and cleaning is done with stored procs and the data extraction is done via a simple Java-based service that runs stored procs to do data extraction. Those data are further used by downstream systems. The project goal is to migrate the system from legacy on-prem infrastructure (old version of Oracle and Solaris) to Linux, cloud version of Oracle and potentially containers. .Net based UI should also be migrated to the cloud. A part of the migration is dealing with data transfer, i.e. migrating legacy Oracle DB (~1TB) to the new cloud version of Oracle.
