Dyn Managed DNS to OCI DNS Migration Script

This script will migrate Dyn Managed DNS zones to OCI's Public DNS.

IMPORTANT INFORMATION

This script will not migrate Dyn Advanced Services at this time.

If your zone includes Advanced Services and you choose to use this script at this time, please see the section at the bottom of this guide for important tips.

USING THE SCRIPT

Requires Python 3.6 or higher

Step 1: Install Python SDK

Follow the installation guide to install and configure the OCI Python SDK.

Step 2: Create OCI Config File (CLI File)

Create a configuration file to use the OCI CLI following instructions provided here

Step 3: Install the Migration Script

Run the following command:

$ pip install oci dnspython requests dyn

Step 4: Usage

python migrate_zone.py example.com dynect-customer-name dynect-user-name

Dynect credentials with permission to read the zone from Dynect are required. The following permissions should be enabled on the Dynect-user-name:

SecondaryGet ZoneGet TSIGGet

Primary zones

In order to migrate a primary zone, the script executes a zone transfer (AXFR) and will therefore require transfers to be allowed to the public IP address of the machine running the script. This is enabled in the "external nameservers" section of your Dyn Managed DNS account. Details and steps can be found on https://help.dyn.com/using-external-nameservers/

For help determining your public IP you can go to http://checkip.dyndns.com/

Secondary zones

If a secondary zone is associated with a TSIG key in Dynect, the script will attempt to look up a TSIG key with the same name in Dynect, and if it is not found, the script will attempt to automatically create the TSIG key in OCI. If the command line option --tsig-key-compartment is used, that is the compartment in which the script will attempt to look for and create TSIG keys.

Help

The default compartment the zones will be migrated to is the root of your OCI tenancy. Users can pass -h or --help (or see below) to add additional arguments such as compartment ocid.

_Migrate zones from Dyn Managed DNS to OCI DNS

positional arguments:

  --zone_names_file ZONE_NAMES_FILE
                        A file containing names of zones to migrate. Required

  --dynect-password DYNECT_PASSWORD
                        Password of the Dynect user
  --oci-compartment OCI_COMPARTMENT
                        OCI compartment to which to migrate the zone
  --oci-config-file OCI_CONFIG_FILE

                        used by zones to be migrated. By default, the same as
                        --oci-compartment
  --ignore-failures     If an error occurs while migrating a zone, skip that
                        zone and continue trying to migrate the rest.
  --no-ignore-failures  If an error occurs while migrating a zone, exit the
                        script without migrating any more zones._

IMPORTANT TIPS (IF YOU HAVE ADVANCED SERVICES AND USE THIS SCRIPT)

Using this script for zones with Advanced Services is not currently supported and will require careful zone adjustments in order to replicate your service within OCI.

If you are migrating a zone with Traffic Director (TD): On the node attached to your TD Service you should expect to see several service-related sub-nodes which will need to be removed prior to configuring the appropriate OCI Traffic Management service.

If you are migrating a zone with other non-TD Advanced Services (such as Traffic Manager, Active Failover or HTTP Redirect): Depending on the configuration of your service, the service node may appear with a record or not appear at all. In all cases, you should be prepared to adjust the node as appropriate for OCI replacement service.

After you have cleaned up your advanced service nodes and are ready to configure the replacement OCI service, you can use the following guides for replicating your Dyn Advanced Service using the appropriate OCI option: https://www.oracle.com/corporate/acquisitions/dyn/technologies/migrate-your-services/
