Preparing for the Upgrade
NOTE:
Do not make other changes to the CLI during the entire upgrade
process. You can ensure that you will not make such changes by opening a
telnet session to the master RE CLI operational mode and issuing the
command. This command locks the configuration procedure.

TIP:
To prevent traffic loss during the upgrade process, we recommend that
you operate the line cards at 50% line rate. This 50% limit must be
maintained per PFE on each line card.
