Editor's note: The following list complements the June article "Data Migration" (Vol. 19, No. 6, p. 27) by Steve Langer, PhD. For the full story, click here.
- Site and vendor should discuss how migration costs and duties will be assigned.
- Contract should permit site-supplied hardware.
- Site should strive to have vendor use an external IHE image archive (or at least institutional storage), with the PACS having only a small cache.
- Site should ensure that the new PACS has a prefetch engine that supports just-in-time migration, can accept all presentation state information from the source PACS, and can create GSPS objects to send to downstream systems.
- Site should insist on broad IHE compliance with applicable integration profiles.
- Contract should include a section on acceptance testing and make the final payment contingent on satisfactory completion of the above requirements; other miscellaneous needs; and successful migration of images from the old PACS, accurately preserving the presentation states.
