Upgrading from versions 1.3 and later

All past versions starting from 1.3 can be upgraded directly to the current version without having to use any intermediate versions.

  1. Follow the normal install procedure, make install step will upgrade the configuration file if it exists in the usual location. All user settings will be kept. However, unidentified content, such as unknown keywords and additional comments, will get cleaned away.

  2. Review the updated configuration file. Refer to comments in the file and the vnstat.conf man page for documentation regarding each setting.

  3. After the configuration file has been updated, restart the daemon (vnstatd) or configure it to use if not previously done already. Note that using a cron entry for updates (something like vnstat -u) is no longer supported and such commands should be removed if still existing.

  4. Upgrades from 1.x to 2.x will result in data being imported from the legacy databases of each interface during the first start of the new daemon (vnstatd) binary. The vnstat and vnstati commands will not be able to access any data before this part of the upgrade has been completed. The legacy databases will be left untouched by the import.
