You can get the main server (Master node) and BI classification updates from the Self-Hosted Portal:
1. Select the Download tab from the Self-Hosted Portal.
2. Scroll down to the Step 2. Download Packages section and click the download button under the Teramind Update section. If you want to just update the BI Classifications (TeraCat), click the download button under the Teramind Classification Update section. The update files have a “.tmu” extension.
3. From you Teramind Dashboard, navigate to the My Account tab:
4. Click the Select update file button under the Software > Update section. Then select the .tmu file you just downloaded. Once you select the file, the button’s label will change to "Update Teramind":
5. Click the Update Teramind button to start the update process.
Note that updating the main server (Master node) this way will also update any associated/slave nodes (app nodes, OCR screen mining nodes, screen mining database nodes, BI nodes, etc.).
However, updating the server will not update the BI classification package. To update it, follow the instructions in this article.
It's a good idea to update the installed Agents once you have updated the server as the server usually comes with an updated Agent. Check out this article to learn how to update the Agent:
