Virtusa's offerings include end-to-end migration including discovery, planning, analysis, migration, and optimization with program management oversight. Virtusa's factory is based on a migration pipeline supported by best-of-breed tools and specialized, core/flex teams.
Phases of migration
• Phase 1: Prepare
You identify the interdependencies between your applications and databases. You also analyze the database workloads to determine the migration categories: from simple rehost (homogeneous) migration to re-architect (heterogeneous) migration.
These tasks are discussed in the following sections:
• Identifying dependencies àBy asking questions such as
§ Is this database directly accessed by any other application?
§ Is the database using database links to fetch data from other databases?
• Qualifying workloads à Understand the current database workload
§ workload qualification tool called AWS Workload Qualification Framework (AWS WQF)
§ It helps identify the complexity of your Oracle and Microsoft SQL Server database migration by analyzing database schemas and code objects, application code, dependencies, performance characteristics.
• Phase 2: Plan
The 6 most common application migration strategies we see are:
§ Re-host (Referred to as a “lift and shift.”)
§ Re-platform (Referred to as “lift, tinker, and shift.”)
§ Re-factor / Re-architect
§ Re-purchase
§ Retire
§ Retain (Referred to as re-visit.)
• Migration Readiness and Planningà(MRP) is a method that consists of tools, processes, and best practices to prepare an enterprise for cloud migration. MRP describes a specific program that AWS Professional Services offers

• Phase 3: Migrate (p. 8)
• Phase 4: Operate and optimize (p. 13)
