system, while the software version previously indicated as permanent is marked 
as old.

Activate ok, relogin                                 <you are logged 
out here>
Restarting system.

login:

Note: Activating the unpacked software upgrade package may cause the 
command line interface (CLI) software to be upgraded as well. 
Therefore, you will be logged out of the system, and will have to log in 
again. Wait until the login prompt appears. This may take up to two 
minutes, depending on your type of hardware platform and whether the 
system reboots.

Note: If you encounter serious problems while running the new 
software version, you can revert to the previous software version (now 
indicated as old). To do this, activate the software version indicated as 
old. When you log in again after having activated the old software 
version, its status is indicated as current for a short while. After about 
one minute, when the system has performed the necessary health checks, 
the current status is changed to permanent.
