If anyone can help/ advise please regarding data migration to a new LIMS:

1)Has anyone recently migrated transfusion data (Group and Screens, antibodies, special requirement flags) to a new LIMs and if so, how many years were migrated?

2) If only a few years were transferred, do your staff have to check the legacy system as part of authorising results, and for how long do you continue this process?

3) Does anyone have evidence of incidents caused by historical legacy records not being transferred over?

4) Would it be acceptable to not migrate any data across? I remember during MHRA inspection few years ago that the inspector indicated that critical NCs were given to sites that had not migrated key info. Is it acceptable to just risk assess not doing this and run with the identified risks?

Many thanks for any help.
