The update process is done in two steps. In the first step the update itself is done by replacing the old references with the new ones and executing a check afterwards. If the check result does not contain error messages, the MDS can then be released. Otherwise, the MDS can be processed manually to correct the errors. For convenience, multiple MDSs can be processed (updated and released) at once.
• The old version for published or owned MDSs is the previous version number
• The old version for accepted MDSs is the previously accepted version number
