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
An alternate definition of process migration is used in integrated circuit design and engineering. Process migration or layout migration in this context is a design flow to change and shrink an existing IC layout to a new process technology node. The implementation of a process migration could be done manually by redrawing the layout feature by feature or by automatic EDA/CAD tools. In load sharing systems, a process is migrated from one node to another using a mechanism called process migration.
