Existing processes or frameworks for secure cloud migration- It classifies the migration process into following types:

• Type      1: Replace

This type of migration replaces one or more legacy component with cloud services. This is least invasive of all types and requires data or business tiers to be migrated to the cloud stack. This type of migration is done by reconfiguring the components and is done to adjust incompatibilities, to use functionalities of the migrating layer. Replace type of migration couldn’t be identified in the selected studies. This particular type is not very popular as much as pure cloud enabler and hence the evidence in probably not available.
