Data migration
Post-migration: After data migration, results are subjected to data verification to determine whether data was accurately translated, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss. Additional documentation and reporting of the migration project is conducted, and once the migration is validated complete, legacy systems may also be decommissioned. Migration close-out meetings will officially end the migration process.
Process migration
The concept of a process is not introduced in this report as processes are a well-known design in operating systems. Process Migration refers to the mobility of executing (or suspended) processes in a distributed computing environment. Usually, this term indicates that a process uses a network to migrate to another machine to continue its execution there. Sometimes the term is used to describe the change in execution from one processor to another processor within the same machine.
