# 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.
