Detailed Application Migration Process

Application migration projects can turn out to be a disaster if not planned properly in a structured manner. Understanding the complexity of applications to be moved and the associated infrastructure is vital to any migration project. Thus, it is essential to clearly identify the requirement, what needs to be captured, plan in a structured way, follow best practices and processes, and then execute.

In this Knowledge Sharing article, Randeep Singh and Dr. Narendra Singh Bhati explain the end-to-end processes and best practices to be followed during application migration. It is based on their experience in migration of infrastructure and associated applications from three existing data centre’s to three new data centre’s involving a stack of 4000 servers and 3 PB of storage across two of the data centres, and a third being lowest in stack, around 500 servers and 600 TB of data. Processes and best practices followed are the same across the three GEO’s and have yielded positive results thus far.
