Occasionally there is a need to copy or move data from one VisibleThread VM to another, for example when setting up a test server with a replica of your production database or migrating your VisibleThread data to a new environment.

 

The basic steps involved to migrate your data are as follows:

1. Export your data from the source VM
2. Copy the exported file to the destination VM
3. Import the data from the export file on the destination VM

 

Note: This process will migrate all users, licenses and data

Export data from source VM

Backup the application data on your old vm by running the following commands on the server (old vm):

cd /home/visiblethread/VisibleThreadTools
./vt-backup.sh

or for Red Hat:

cd /opt/visiblethread/VisibleThreadTools
./vt-backup.sh

This will create a backup file in the /home/visiblethread/VisibleThreadTools/vtbackups folder

 

Copy export data file to destination VM

Using ftp or some other means copy the export file created above to your new VM. For details on how to connect to your VM using ftp see here: https://visiblethread.zendesk.com/hc/en-us/articles/214225546-Accessing-the-VisibleThread-Virtual-Appliance-using-Secure-FTP

 

Import data on the destination VM

Open an ssh session on the destination vm and import the data (exported above) by typing the following commands:

cd /home/visiblethread/VisibleThreadTools
./vt-restore.sh <backup-file.tar.gz>

or for Red Hat:

cd /opt/visiblethread/VisibleThreadTools
./vt-restore.sh <backup-file.tar.gz>

where "<backup-file.tar.gz>" is the name of the export file created in step 1.

 

Copy over any custom certificates to the destination VM

Our software comes with self-signed certificates, but if you've followed our guide on installing SSL certificates you will need to copy those certificates over to the new server and update your Apache configuration file.

On Ubuntu servers, the certificate files and Apache config are stored in: 

Certs: /home/visiblethread/VisibleThreadTools/cert/
Apache: /etc/apache2/sites-enabled/000-default.conf

On Red Hat servers, the certificate files and Apache config are stored in:

Certs: /opt/visiblethread/VisibleThreadTools/cert/
Apache: /etc/httpd/conf.d/visiblethread.conf

 

Once the certificates are copied to the new server, reference them in the Apache configuration file, then restart the services.

 

Apache file lines:

# Ubuntu
SSLCertificateFile      /home/visiblethread/cert/myserver.com.crt
SSLCertificateKeyFile   /home/visiblethread/cert/myserver.com.key

# If a chain/intermediate key is needed add the following below SSLCertificateKeyFile:
SSLCertificateChainFile /home/visiblethread/cert/myserverchain.com.crt

# On RedHat Deployment
SSLCertificateFile      /opt/visiblethread/cert/myserver.com.crt 
SSLCertificateKeyFile   /opt/visiblethread/cert/myserver.com.key

# If a chain/intermediate key is needed add the following below SSLCertificateKeyFile:
SSLCertificateChainFile /opt/visiblethread/cert/myserverchain.com.crt

 

Restart services on Ubuntu:

sudo service supervisor restart

Restart services on Red Hat

sudo systemctl restart visiblethread-docs

 

Verify the VisibleThread application is working correctly

Once the restore process is complete ask a user to log in to the VisibleThread application on the new VM. Verify the data is as expected.
