  Installation and Upgrade Notes

To ensure a successful upgrade, you must complete some steps before you start the upgrade process. For 
details on these prerequisites, see 
.
Installation and Upgrade Notes
Read through and consider the installation and upgrade impacts listed in this section. 
When you upgrade AsyncOS for Email from the web interface or Command Line Interface (CLI), the 
configuration is saved to file in the /configuration/upgrade directory. You can access the upgrade 
directory using an FTP client. Each configuration file name is appended with the version number, and 
passwords in the configuration file are masked so they are not human readable.
You must be logged in as the admin to upgrade. Also, you must reboot the appliance after upgrading.
Pre-upgrade Notes
Please be aware of the following upgrade impacts:
Do Not Upgrade If LDAP Queries Include Uppercase Letters 
If your deployment uses uppercase letters in LDAP queries, upgrading to this release is not 
recommended. For details, visit 
AsyncOS Reversion
If you plan to revert to an earlier version of AsyncOS, such as AsyncOS 7.5.1 or AsyncOS 7.1.5, you 
must update your network settings to use only IPv4 addresses before performing the reversion. Earlier 
releases of AsyncOS for Email do not support IPv6 and any settings that use IPv6 addresses will be reset.
Warning
Cisco does not support reverting your appliances to AsyncOS 7.3.x after you have upgraded them to 
AsyncOS 8.0.
Re-enable FIPS Mode
If you have upgraded from AsyncOS 7.3, the appliance will not be running in FIPS mode after the 
upgrade. You will need to import or generate new certificates and keys after the upgrade since the 
appliance will not be access the private keys on the HSM.
Re-enable SNMP
SNMP does not start when you boot the appliance after upgrading to AsyncOS 7.6. Use snmpconfig -> 
setup
 and then commit to enable it.
