/**
 * This Update script will update all browser and os archives of UserSettings and DevicesDetection plugin
 *
 * In the future only DevicesDetection will handle browser and os archives, so we try to rename all existing archives
 * of UserSettings plugin to their corresponding archive name in DevicesDetection plugin:
 * - *UserSettings_browser* will now be *DevicesDetection_browserVersions*
 * - *UserSettings_os* will now be *DevicesDetection_osVersions*
 *
 * Unlike DevicesDetection plugin, the UserSettings plugin did not store archives holding the os and browser data without
 * their version number. The "version-less" reports were always generated out of the "version-containing" archives .
 * For big archives (month/year) that meant that some of the data was truncated, due to the datatable entry limit.
 * To avoid that data loss / inaccuracy in the future, DevicesDetection plugin will also store archives without the version.
 * For data archived after DevicesDetection plugin was enabled, those archive already exist. As we are removing the
 * UserSettings reports, there is a fallback in DevicesDetection API to build the report out of the datatable with versions.
 *
 * NOTE: Some archives might not contain "all" data.
 * That might have happened directly after the day DevicesDetection plugin was enabled. For the days before, there were
 * no archives calculated. So week/month/year archives will only contain data for the days, where archives were generated
 * To find a date after which it is safe to use DevicesDetection archives we need to find the first day-archive that
 * contains DevicesDetection data. Day archives will always contain full data, but week/month/year archives may not.
 * So we need to recreate those week/month/year archives.
