Use File System V7 or older - old storage will be used in V7 format without any changes to its structure. All calls to the V7 file system will be passed over the new API -> old API wrapper.
All previously recorded data (video, audio, text, alarms etc.) will be accessible after the DVMS update.
Use File System V8/V9 and remove old data - old storage will be erased and formatted to a new File System format. All previously recorded data is lost.
Use File System​ V8/V9 and leave old data - old storage will be left as is, but DVMS will be configured to use a new File System format.
This is useful if there is some additional disk that can be used for new data, and there is some need to keep old storage for some time to access previously recorded data.
Previous data can be opened as an archive in Spotter. The installer will create archive information if this option is selected in the installer.
