RealNetworks releases new versions of SAFR almost every month that contain additional features. You will occasionally want to upgrade your SAFR Server(s) to the latest version in order to take advantage of the new features. To upgrade your SAFR Server(s), follow the instructions below.
To upgrade your SAFR Server cluster to the latest version of SAFR, do the following:
Prevent new faces from being added during the upgrade by performing one of the following:.
Stop the CoVi service from running on all secondary SAFR Servers, OR
Stop all clients (i.e. VIRGO video feeds, Desktop clients, and Mobile clients) that are adding new faces.
Make a backup of your Primary SAFR Server, as described in the SAFR Server Backup documentation. Note: Backup and restore should only be performed for the primary server. Secondary servers will synchronize automatically with the primary server.
Update the primary SAFR Server by running the latest SAFR Platform installer. While the primary server is upgrading:
The system will be down unless an external load balancer is being used.
Even when an external load balancer is being used, there will be about 2-20 seconds where newly generated events might be dropped.
Live video streams will be down.
Update the secondary SAFR Servers by running the latest SAFR Platform installer on each of them.
Restart the CoVi service on all the secondary servers, if you stopped them in Step #1. Similarly, you can resume submitting faces on all clients.
