Installation and Upgrade Guidelines 
 

An FTP or SSH server is required to download new software to the USRM. 

Before performing the upgrade procedure, make sure the following requirements are 
met: 



 

The desired USRM software release has already been uploaded to the FTP server. 



 

If the DNCS is being used as the FTP or SSH server, make sure that the desired 
USRM release is located in the /export/home/dncs directory. 



 

If the DNCS is being used as an SSH server, make sure that the Provisionkeys 
application has been run on each of the servers. 



 

A backup of the existing USRM database has been completed prior to upgrading 
to be prepared in case a rollback to the previous version is desired. A backup can 
be created from any directory in the USRM by typing usrmbackup at the 
command line prompt. The backup file will be stored in the /root directory. We 
recommend that this backup file be copied to and saved in a secure location in 
case it is needed in the future. 

Note: A downgrade from USRM 2.1.4 to USRM 1.x requires the installation of a 1.x 
database as part of the procedure. If a 1.x database does not exist, all persistdata will 
be lost during the downgrade. 

With the introduction of VOD Session Management capabilities to the USRM, it is 
now required to keep track of all traffic on all GigE ports on all QAMs. With this in 
mind, we now require that the Edge Input IP address(es) be included for all QAMs. 
If you have configuration files, the Edge Input address(es) should be added to these 
files. 
Note: Failure to populate Edge Input Address(es) will result in session setup 
failures.
