Challenges and goals

Their product is in running condition in the production and lots of traffic is coming to them. Keeping the traffic problem in mind, the client decided in the first step, to migrate all the data and once the development team gets all the understanding of the existing product then update/revamp the software. Scale the software very fast because of the load on the system.

"Our goal was to enhance the performance and quality of an existing cloud-based software product by migrating all the data in an efficient way and document everything."
