Cisco Cisco IOS XR Software Release 3.2

You only need to back up your files that you have stored on these boot flashes. If you have not stored 
any files on these boot flashes, then this step is not necessary. Generally, no user will store their files on 
LC/SP bootflash. But user could store some of the configuration files on the RP or standby RP bootflash. 
These files need to be backed up. You can use copy command to back up these files to the harddisk.

Use the following procedure to upgrade the Cisco IOS XR software from Release 3.0.1 to Release 3.2.2 
on a Cisco CRS-1:

Add the required PIE files to disk:

RP/0/RP0/CPU0:router# install add <device or tftp/ftp/rcp>/PIE_filename to disk0: sync

Step 1 must be repeated for each of the PIE files listed in 

 or all of the PIE 

files can be added together in a single install add command. To add all PIE files using a single command, 
list all of the PIE files (including their source) within the install add command as follows:

RP/0/RP0/CPU0:router# install add <device or tftp/ftp/rcp>/comp-hfr-mini.pie-3.2.2 <device 
or tftp/ftp/rcp>/hfr-mcast.pie-3.2.2 <device or tftp/ftp/rcp>/hfr-mgbl-p.pie-3.2.2 <device 
or tftp/ftp/rcp>/hfr-mpls-p.pie-3.2.2 <device or tftp/ftp/rcp>/hfr-k9sec-p.pie-3.2.2 to 
disk0: sync

The use of sync option prevents the user from issuing any other command while the installation is in 
process.

Activate all of the added packages together:

RP/0/RP0/CPU0:router# install activate disk0:comp-hfr-mini-3.2.2 disk0:hfr-mcast-3.2.2 
disk0:hfr-mgbl-3.2.2 disk0:hfr-k9sec-3.2.2 disk0:hfr-mpls-3.2.2 sync

The output of install add command issued in Step 1 provides the list of names of packages to be used 
in install activate command.

The use of sync option prevents the user from issuing any other command while the installation is in 
process.

As this is an impactful upgrade, the router reloads at the end of activation to start using the new 
packages.
