= Updating to Reggie 2.9 = Updating to Reggie 2.9 requires a manual update to the 'creation date' for all `Blood` samples. Due to a bug (see #429) the sampling date was only stored in the `BloodSamplingDateTime` annotation and the 'creation date' was left empty. The correct behavior which was fixed by #429 is to store the date part also in the 'creation date' field. Follow this procedure: == 1. Update to Reggie 2.9 == == 2. Export a tab-separated file with at least the ID and `BloodSamplingDateTime` values == * Go to the samples list page and filter on `Blood` items. Make sure that no other filter is present. * Export the ID and `BloodSamplingDateTime` values. Save the file on the BASE file system. == 3. Import the tab-separated file to update the 'creation date' == * Use the 'Sample importer' wizard and select the file that was created by the export. * The 'Mode' parameter can be set to 'update' just in case... * Use the 'Test with file' function to set up column mappings for the '!InternalId' and 'Created' properties. If all goes well, the dates should now have been copied from the `BloodSamplingDateTime` annotation to the 'creation date' property.
