Release 10.1 and later are compatible with signature set version 10.8.x and above. If you are upgrading from any 9.x version, during installation, the signature set bundled with the installer will be imported to the Manager automatically.
Increase in memory size for handling signature sets
With a growing number of threats, the frequency of signature set updates and the number of attacks in each update constantly increase. As a means to accommodate a larger signature set size in the future, the memory size allocated to signature sets on the Sensor has been increased.
Notes for upgrading Manager running lite signature set
Release 10.1 and later are compatible with signature set version 10.8.x and above. When you upgrade your Manager from version 9.x to 10.1, the Manager installer automatically checks for availability of signature set version 10.8.x. If your Manager is running a signature set version 10.8.x, the installer re-imports the same signature set from the update server. Whereas, if your Manager is running a signature set older compared to 10.8.x, the installer downloads the signature set bundled with the Manager upgrade file from the update server. But, when you are using a lite signature set, the Manager installer fails to re-import the signature set due to unavailability of lite signature set in the update server. In such scenarios, the Manager installer displays a warning message, requesting you to re-import the signature set manually. For successful upgrade, you should manually re-import the required lite signature set after the upgrade. Trellix recommends you to re-import the latest lite signature set version available in the update server.
