Migrating a Centova Cast installation is a very advanced procedure which should only be performed by qualified systems administrators.  Be sure to backup your data carefully in advance.

DO NOT decommission your old server, or update DNS to point to your new server, until you have successfully performed the migration and verified that the streams are working on the new server.

To migrate a Centova Cast installation from Server A to Server B:

1. Login to your client account at centova.com.  Click "Manage Product Licenses", then click on your Centova Cast license.  Then, click the "Re-issue license" link.
   
   
2. Install Centova Cast on Server B.  Important: Be sure to install the same version of Centova Cast that you are using on Server A.  You may want to upgrade Server A to the latest version before performing the migration.
   
   Be sure to install it exactly as you did on Server A (using the same paths and so-on, and configuring it to use the same server/source software) otherwise your migrated configuration data will not work.
   
   
3. Backup your Centova Cast database on Server A.  You can do this using the "mysqldump" command via SSH, or using a web-based tool such as phpMyAdmin.
   
   For example:
   mysqldump -uroot -p CAST_DB_NAME > cast_db_backup.sql
   
   
4. Backup the /home/centovacast/vhosts/ directory on Server A, maintaining file/directory permissions (i.e., using tar or rsync for the backup).
   
   For example:
   cd /home/centovacast/vhosts
   tar czvf /cast_backup.tar.gz *
   
   
5. On Server B, restore the database backup you made in step 2.  You can do this using the "mysql" command via SSH, or using a web-based tool such as phpMyAdmin.
   
   For example:
   cat cast_db_backup.sql | mysql -uroot -p CAST_DB_NAME
   
   
6. On Server B, restore the file backup you made in step 3, maintaining file/directory permissions.  For example:
   
   cd /home/centovacast/vhosts
   tar xzvf /cast_backup.tar.gz
   
   
7. Update ownership of your virtual hosts by running:
   
   chown -R centovacast.centovacast /home/centovacast/vhosts
   
   
8. Update the Centova Cast UID/GID in your Centova Cast database on Server B.  You can do this using the "mysql" command via SSH, or using a web-based tool such as phpMyAdmin.
   
   To determine the new UID/GID of the 'centovacast' account, run this command on Server B:
   id centovacast
   
   This will display something like:
   uid=1009(centovacast) gid=1010(centovacast) groups=1010(centovacast)
   
   In this case, your Centova Cast UID would be 1009, and your Centova Cast GID would be 1010. 
   
   Next, update the "ccuid" and "ccgid" fields in the "settings" table in the Centova Cast database on Server B.  For example, if your UID is 1009 and your GID is 1010, you might use this query:
   
   UPDATE settings SET ccuid='1009',ccgid='1010';
   
   

At this point, you should have a working Centova Cast installation on Server B.  Login to Server B and test your streams to make sure that they are working.
