5 Phase Approach 1. Migration Preparation and business planning - Stand alone little planning. In most cases inter-connectivity requires very detail planning and prep for technical and business side of operation right obj determines and type of benefit you see. it starts with foundation experience and developing preliminary business case for migration Write done: objective to meet age and architecture of existing applications Application constraints output is : Types of benefit you see and begins 2. Portfolio discovery and planning take deeper look at IT portfolio find dependencies what migration works for each application focus on app discovery building use case for each application etc AWS application discover service  can assist. 3/4. Designing, migration and validating your applications focus is from portfolio level to application level for designing. migrating  and validating 6 R's you can take help from partners AWS server migration

Once the organisation has decided to do cloud migration you can refer below framework / methodology to proceed with the migration MRA ( Migration Readiness Assessment) ->  MRP ( Migration Readiness & Planning) -> Migration and Operation Apply CAF ( AWS Cloud Adoption Framework to above) CAF is AWS learning with all its customer to understanding what has worked , can be improved and given comprehensive approach . It identifies and focus areas that are critical to cloud adoption. MRA is: (Helps you assess Org capabilities, readiness and commitment to migrate to cloud ) Rapid Discovery Directional Business Use Case - high level calculation of potential cost saving & increase business agility associated with the aws migration MRP: ( build capabilities to migrate to & Operate to in cloud) OUTPUT is - detail migration plan is build Discovery and planning,  -  Define app patterns and planning , get backlog Landing Zone ,  - Foundation AWS infrastructur
