About this task
Note: To upgrade releases prior to
Release 10.0, you must uninstall the software before you can upgrade. The LCS85
installer prompts you to uninstall the previous release. Although the installer
allows an upgrade from Release 10.0 to Release 11.0, best practice is to uninstall
the previous version.
Important: The
Advanced Security Enabled feature indicates whether the site uses the advanced
security settings. This attribute provides an improved layer of security between
Metasys Site Directors and devices. With this attribute set to true,
backward-compatible methods of communication between the Site Director and its
network engines are disabled, which means a Site Director at Release 10.0 or later
discards all communication attempts from network engines prior to Release 10.0. At
Release 11.0, the Advanced Security Enabled attribute is defaulted to True. This setting applies to the entire site, so
change this attribute set to False if you
have any network engines prior to Release 10.0. When you change this attribute to
True, a user message appears to indicate
that all network engines prior to Release 10.0 remain online, but are disconnected
from the site because they no longer communicate with the Site Director. If this
message appears, click OK to continue and set the attribute to True, or Cancel to keep the attribute set to
False.
Note: For an LCS85 at Release 10.0
or later, there may be a requirement to run Metasys on a lower priority Network
Interface Card (NIC). In cases like this, you must manually modify the
N50.ini
file to use the lower priority NIC as you do
not get the option at install to chose the NIC.
