Restore a Chronograf database
Chronograf uses Bolt to store Chronograf-specific key-value data. Generally speaking, you should never have to manually administer your internal Chronograf database. However, rolling back to a previous version of Chronograf does require restoring the data and data-structure specific to that version.
Chronograf’s internal database,
chronograf-v1.db, is stored at your specified
by default, is the current working directory where the
chronograf binary is executed.
In the upgrade process, an unmodified backup of your Chronograf data is stored inside the
backup directory before any necessary migrations are run.
This is done as a convenience in case issues arise with the data migrations
or the upgrade process in general.

Each backup file is appended with the corresponding Chronograf version.
For example, if you moved from Chronograf 18.104.22.168 to 1.8.0, there will be a

Roll back to a previous version
If there is an issue during the upgrade process or you simply want/need to roll back to an earlier version of Chronograf, you must restore the data file associated with that specific version, then downgrade and restart Chronograf.
The process is as follows:
1. Locate your desired backup file
backup directory, locate the database file with a the appended Chronograf
version that corresponds to the version to which you are rolling back.
For example, if rolling back to 184.108.40.206, find
2. Stop your Chronograf server
Stop the Chronograf server by killing the
3. Replace your current database with the backup
Remove the current database file and replace it with the desired backup file:
# Remove the current database rm chronograf-v1.db # Replace it with the desired backup file cp backup/chronograf-v1.db.220.127.116.11 chronograf-v1.db
4. Install the desired Chronograf version
5. Start the Chronograf server
Restart the Chronograf server.
Chronograf will use the
chronograf-v1.db in the current working directory.
Rerun update migrations
This process can also be used to rerun Chronograf update migrations. Go through steps 1-5, but on step 3 select the backup you want to use as a base for the migrations. When Chronograf starts again, it will automatically run the data migrations required for the installed version.
