Upgrading Anzo Unstructured
The steps to upgrade the Anzo Unstructured (AU) software are the same as the installation instructions in Installing Anzo Unstructured. When you update the existing installation, each prompt defaults to the value that is specified for the current deployment. You can press Enter through the prompts to retain the existing settings. The last step in the process, however, asks if you want to overwrite files in the <AnzoDU_install_path>/etc directory that have been modified. Cambridge Semantics recommends that you choose ya (Yes To All) to overwrite all files in that directory so that important options from the version you are upgrading to are deployed to your environment. If you have customized files in the etc directory, create a backup copy of the directory before starting the upgrade so that you can refer to the backup files when customizing the new version.
When upgrading the AU software, the Leader and Worker applications must be upgraded at the same time using the same installer so that the software versions are identical across the cluster. You cannot upgrade the Worker nodes without upgrading the Leader and vice versa.
After the upgrade, make sure that you restart the Leader and Worker applications as well as the following Anzo services:
- Anzo Server Akka Cluster Integration
- Anzo Unstructured Distributed
