The preUpgradeChecks scripts are contained in the EC PUC kit. This kit must be 
downloaded from the following Cisco URL: 

https://upload.cisco.com/cgi-
bin/swc/fileexg/main.cgi?CONTYPES=ITE_LT

 

You will download the PUC ISO and the pre-upgrade document, System Release Pre-
Upgrade Checks (part number OL-32656). The PUC ISO contains all of the scripts 
necessary to complete the checks. The document contains the instructions for 
executing the pre-upgrade checks script. 

These files should be downloaded to a shared (NFS) storage device accessible by the 
EC. If a shared device is not available, download the files to a PC that has access to 
the EC and SFTP them to the EC. 

The preUpgradeChecks script validates your system for upgrade eligibility. The 
preUpgradeChecks script should be run 2 or more weeks prior to your upgrade in 
order to ensure that enough time exists to resolve any major issues or 
incompatibilities that may affect your ability to upgrade. The preUpgradeChecks 
script should be run again just before you upgrade to validate the system.   

Important: The preUpgradeChecks scripts must be run on each EC that will be 
upgraded (for example, EC and the Remote Network Control Server (RNCS)).
