A VNA Does Not Require Data Migration or Conversion
Data migration when exchanging PACS vendors has become a major expense, requiring significant resources and delaying new PACS implementations. Migrating data to a format that might have to be migrated again in a couple of years does not make sense. A much better choice would be to migrate it once to an open and widely supported standard.
Of course, this does not mean that the actual objects would stay on the same physical media forever. As hardware storage technology improves, data might still be moved. However, the data formats would not change and there would be no disruption of the image availability.
The same applies for storage software technologies, improvements to support different database technologies, and virtual storage architectures. Again, the latter should not impact the image availability and might be done to improve performance and cost rather than a forced, costly migration because of vendor changes.
- Data migration has become a major expense
- Migrating data once to an open and widely supported standard is ideal
- As technology and storage capabilities improve, the data should be able to be migrated easily
