In order to reduce our ongoing code maintenance workload, we are planning to phase out support for "legacy" study archive formats. These are file formats used by DataFax for dataset and visit map definitions. For many versions, LabKey Server has preferred XML-based formats for this same data. The usage scenario where these legacy formats were being generated by an external system long ago migrated to use the new file formats, and we are not aware of other uses.

We are planning to remove the ability to export studies in the legacy file format as part of 14.3. We will continue to import the legacy formats though. In previous releases, you could export using the DataFax format by choosing "Legacy file format" option in the study or folder export user interface:

Then, in version 15.1, we plan to remove the ability to import the legacy file formats. In 14.3 and earlier, the server automatically detected the file format option and used the appropriate import parsers.

Please let us know if this plan conflicts with your current usage of the study archive file formats.

Thanks,
Josh
