About PACS Data Migration
Why Migrate?
Whenever a PACS is replaced by a successor system, plans must be made for access to historical data in the existing legacy system. The choices are to either keep the legacy archive running including an interface to new system, or migrate the data to the new system. The size and complexity of the data transfer task is such that data migration is a project element that must be explicitly planned and budgeted for.
