Migration—6 'R's
Retain
RepurchaseRehost
RefactorRetire
Replatform
• Customers will keep host/application in
their source environment
• Minimal analysis/validation of scope and
application affinity
• Dependency on integrating service
management
• Application and host decommission on
source
• No migration to target
• Application owner approvals needed
• Like-for-like application migration to target
cloud
• Minimal effort to make the application work
on the target cloud infrastructure (minimal
application layout change)
• Storage migration will be needed (without
conversion)
• Up-version of the OS and/or database onto
the target cloud
• Some level of application changes
• Application reinstallation on the target
• Database to Amazon RDS or Amazon Aurora
• OS and/or database porting
• Middleware and application change to cloud
service offering
• Data conversion; database transition to
different engine
• Use SaaS-based offerings, application
architecture changes may require porting
• Middleware, data modernization; application
consolidation/stacking

Staffing Commitment
The Readiness and Planning Engagement is based on an Immersion approach that
requires a core team of customer staff to be available full-time during at least 3 days per
week.
Sessions are recorded to capture a history of discussions and decisions, and enable staff
that are impacted by emergency events to be able to review sessions that they missed.
