Before completing the upgrade
During the Apply process of upgrading to a new version of code, the VPN Router
copies files from your current version of software to the new version before the
VPN Router is rebooted. Because processes are still running, the copying of files
can potentially cause file access problems.
To minimize the possibility of file access problems after the upgrade, Nortel
recommends that you perform the following steps.
1 Disable new logins. See “Disabling new logins” on page 60 for the procedure.
2 Log off all active tunnel sessions.
a Select Status > Sessions.
b Scroll to the bottom of the window and click both Log Off buttons to log
off all non-administrative users and all branch office connections.
3 Disable RADIUS accounting.
a Select Servers > RADIUS ACCT and disable all of the following
options:
— Internal RADIUS Accounting
— Interim RADIUS Accounting Record
Note: These sessions are logged off during the Apply process
