Many of the servers for migration were in production and functional critical to wide range of business operations of client, such as HR, finance, marketing etc, which requires extensive understanding of not only server migration, but applications domain knowledge.

As the on-premise servers were running for years, most of the middlewares and OS were out dated. client required to streamline all Linux instances to AWS Linux and Windows instances to Windows 2012 R2 during migration, as well as middleware upgrade.

Client also wanted to take this chance to enroll the infrastructure into the DevOps process for CI/CD that was newly setup.

Solution

1Cloudstar consultant conducted in-depth server by server study and interview with relevant users and stakeholders. Then one detailed project plan and migration schedule with highlighted critical points and potential risks was drafted and presented to client.
