Migration on Gravity

Migration as a proxy

Mon, 01 Jan 0001 00:00:00 +0000

A universal method of migrating DNS records to Gravity is to setup a Zone to forward requests to an existing DNS Server and save the results into Gravity.

This can be done by using the following handler configuration on a zone:

- type: memory
- type: etcd
- type: forward_ip
 to:
 - <IP Address of the existing DNS Server(s)>
 cache_ttl: -2

With this configuration, Gravity can be configured as the default DNS Server for a domain, and it will forward requests to the configured upstream DNS servers and permanently write the results into its database.

Migrating from Bind

(requires Gravity v0.24+)

Gravity can import DNS records from Bind zonefiles.

Retrieving the zone file

Retrieving the zone file will depend on the setup of your Bind server. In most cases, this file will be in /etc/bind/.

Some other DNS servers also provide the option of exporting records as DNS, these files are also compatible with Gravity.

Import data into Gravity

Web

Click on the Create button on the DNS Zones page and enter the domain for the new zone. On the next page select Import and continue. Select the zone file from above. Gravity will import all records into the new scope.

Migrating from Opensense

(requires Gravity v0.24+)

Gravity can import DNS records from Opnsense backups.

Exporting records

In the Opnsense web interface, export a backup under System -> Configuration -> Backups. Make sure to not include RRD data (default) and not encrypt the configuration file.
