Complete the following tasks to prepare for the upgrade to NetWitness Platform 11.5.
Task 1. (Optional) Remove Legacy Package Repositories
Perform this task to free up space by removing unused repositories from previous releases from your system.
- Determine the version of the oldest NetWitness Platform host in your environment by reviewing the host list in the Admin user interface, or by running the following command on the NW Server: upgrade-cli-client --list
- You can safely remove all legacy package repository folders located at /var/netwitness/common/repo/<version> on the NW Server for all versions prior the baseline major release version of the oldest active host in the environment.
- If the oldest host version is 11.4.x.x (for example, 18.104.22.168), you can safely remove 11.0.x.x, 11.1.x.x, 11.2.x.x, and 11.3.x.x repository folders. However, do not remove repository versions greater than or equal to 22.214.171.124.
- If the oldest host version is 11.3.x.x, you can safely remove 11.0.x.x, 11.1.x.x, and 11.2.x.x repository folders. However, do not remove repository versions greater than or equal to 126.96.36.199.
Task 2. (Optional) Ensure that Any Respond Normalization Script Customizations Are in the Custom Files
For upgrades from 11.4 to 11.5.x, there are no backups of the normalization script files since customizations are added to separate custom_normalize script files. These script files are in the /var/lib/netwitness/respond-server/scripts directory. If you have any customizations, add them to the normalization files with the custom prefix.
