Tranfer All CDRouter Data to a New System (cdrouter-clone tool)

Introduction

If you have recently upgraded your CDRouter system hardware to a new NTA1000 platform, this article will help you transfer all existing configuration data and test results to the new system.

The cdrouter-clone utility, available with the CDRouter software installed on your NTA1000, can make an exact copy of your old system’s CDRouter database, so there is no need to import or manually copy anything, and you can resume testing right where you left off.

Background

The CDRouter database and all test data, including config files, packages, devices, and test results are stored in a central location on the system.

This test ‘data’ is stored within the /usr/cdrouter-data directory and its sub-directoires. The cdrouter-clone utility will automatically copy this entire directory structure to your new NTA1000 hardware.

Requirements

The cdrouter-clone utility is available with an installation of the CDRouter software.
Any existing CDRouter data that is present on the new NTA1000 will be deleted once the cloning process starts. Please contact support@qacafe.com if you have any concerns about preserving data that you may have created on the new NTA1000 prior to running this procedure.
The eth0 management interface of both machines must be connected to the same network so that the NTA1000 can connect to the old CDRouter system via SSH.
You must have the IP address and 'root' password of the ‘old’ CDRouter system. You will be prompted to enter this password at the start of the procedure.
Make sure there are no tests running on either system. The cdrouter-clone utility will automatically shut down CDRouter on both systems which will interrupt any tests that may currently be running.
Any data or files that are not within the /usr/cdrouter-data/ directory will not be copied by cdrouter-clone. You will need to manually copy this data to the new NTA1000. (For example, if you have any files in /home/qacafe)

Data transfer steps

The data transfer process is fully automated. Simply open a CLI terminal on the new NTA1000 and run the cdrouter-clone utility with the IP address of the old system that you want to clone.

The cdrouter-clone utility will SSH to the root account of the old system and transfer an exact copy of the CDRouter test data to the new NTA1000.

Log in to the root user account of the NTA1000 and open a command terminal. Run the cdrouter-clone program at the command prompt with the IP address of the old CDRouter system that you want to copy data from (e.g. “10.1.1.25”). The cdrouter-clone utility can be found in the /usr/cdrouter/bin/ directory on the NTA1000.
```
        [root@nta1000 ~]# /usr/cdrouter/bin/cdrouter-clone 10.1.1.25
```

The cdrouter-clone utility will open an SSH connection to the old CDRouter system and prompt you for the root user password on that system. You may also see a message containing the public key fingerprint of that system.

Enter ‘yes’ to confirm that you want to proceed with the SSH connection.

    [root@nta1000 ~]# /usr/cdrouter/bin/cdrouter-clone 10.1.1.25
    The authenticity of host '10.1.1.25:22 (10.1.1.25:22)' can't be established.
    ECDSA key fingerprint is d1:18:48:db:be:6b:0f:f3:1b:8d:21:61:df:7c:28:c0.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '10.1.1.25:22' (ECDSA) to the list of known hosts
    root@10.1.1.25's password:

After connecting and verifying the data on the remote system, cdrouter-clone will print a warning message that the local CDRouter data and results will be deleted, and ask you to confirm if you want to continue.

Enter ‘yes’ to confirm and proceed with the cloning process.

    root@10.1.1.25's password:

    WARNING:

        * 61.18 GiB will be copied from 10.1.1.25 to this system.

        * This program will erase the local CDRouter data directory of this system
          and replace it with the data from 10.1.1.25

        * All data that is currently in /usr/cdrouter-data will be PERMANENTLY DELETED.
          THIS ACTION CANNOT BE UNDONE AND MUST NOT BE INTERRUPTED ONCE STARTED.

    Are you sure you want to do this (yes/no)? yes

The cdrouter-clone utility will shutdown CDRouter on both systems if necessary, and then proceed to copy all of the data from the old system to your NTA1000.

Do not to restart CDRouter or reboot your systems while the data transfer is in progress.
```

```
When the data transfer is finished, cdrouter-clone will automatically restart CDRouter

After the cloning has completed, the CDRouter web interface on the NTA1000 should appear identical to the one that was running on your old system. You may now connect your CPE devices and resume your testing.

Note that you may need to update some of your config files if the network interface names (ie. 'eth1', 'wlan0', etc.) are different on the NTA1000 than they were on your old system.

Also note that any custom testpaths configured in the CDRouter database will produce warnings until you have manually copied the custom test modules from the old system to the NTA1000. Go to the Preferences page in the CDRouter web interface if you need to update or delete any custom testpaths

If you encounter any problems while using the cdrouter-clone utility, please contact support@qacafe.com for assistance.
