Discovery & planning

  • Identify data required for the migration.
  • Define Application patterns.
  • Priorities migrations.
  • Suggests incomplete data.
  • This work stream helps to understand what qualifies for a Pilot Light Migration.
  • This section also defines about RPO and RTO.

The data elements can be categorized into 4.
ApplicationServerNetwork , Storage



  • Extract important data to understand connection information , interdepend of Apps , servers , patterns etc..
  • Performance metrics helps to understand to provision the right size on Cloud
  • Tagging and Service naming helps to identify the group during the migration.
  • Prioritize according to Business criticality, Environment Priority(Dev, Test, Prod Environment) , Application Complexity(least complex app will be a good candidate to migrate first)

Choosing Portfolio Discovery tools

  • Going Agent or Agentless , give you more insight into data.
  • Dependency Discovery – Server Level , Application Level.
  • Performance Discovery
  • Visualization and reporting tools
  • Cost Analysis Tools -On-premises Constraints

Evaluate and choose discovery tools based on the needs of Migration Planning, Customer requirements & Environment Constraints.

Migration Business Case

It is also important to understand the migration cost estimate, TCO Modeling (AWS Pricing Calculator), options to optimize.

Lavages the agile mythology , project control & Business communication Principal to drive the execution of each domain by sprints.
The Pilot application are identified and migrated during the MRP which helps to understand different types of AWS services & tools.
