Migration Strategies

• 6R’s of Migration
  • Retain: We have decided to run application in on-prem itself
  • Retire: Stop active development and move to new product line
  • Repurchase: Try to purchase a new Saas based application which exactly does what your current application is doing.
  • Re-host: Run it on the cloud exactly like on-prem (lift and shift)
  • Re-platform: Make small decisions about running the applications of different deployment model (Paas) (lift, tinker and shift)
  • Refactor/Re-architect: Rewrite the application to make it cloud native and modern architecture compliant.
