Cisco Cisco IOS XR Software Release 3.2

RP/0/0/CPU0:router(admin)# install add <device or tftp/ftp/rcp>/c12k-mini.pie-3.2.2 <device 
or tftp/ftp/rcp>/c12k-mcast.pie-3.2.2 <device or tftp/ftp/rcp>/c12k-mgbl.pie-3.2.2 <device 
or tftp/ftp/rcp>/c12k-mpls.pie-3.2.2 <device or tftp/ftp/rcp>/c12k-k9sec.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/0/0/CPU0:router(admin)# install activate disk0:<device or tftp/ftp/rcp 
package_name_or_alias> disk0:package_name_or_alias <..> sync

The output from 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 upgrade is a full upgrade, the router reloads at the end of activation to start using the packages.

Verify system stability through commands described in 

issues are detected or the newly activated software must be backed out for any reason, follow the steps 
described in 

 to roll back the software configuration to a previous 

rollback point.

Commit the newly activated software from admin mode:

RP/0/0/CPU0:router# admin 
RP/0/0/CPU0:router(admin)# install commit

Each install activate, deactivate, or commit operation automatically creates a rollback point, so that a 
software configuration can be reverted to a previous software configuration. Use the following 
procedure to downgrade Cisco IOS XR software to a previous rollback point.

You can roll back to a previous software configuration only if all packages in that software configuration 
are still present on disk. If you removed a package with the install remove command, then a rollback 
operation to that package fails. To resolve this issue, use the install add command to re-install any 
previously removed packages.
