Upgrade the Splunk Add-on Builder

Use Splunk Web to upgrade the Add-on Builder.

Because the Splunk Add-on Builder version 4.0.0 and later is compatible with only Python 3, version 3.0.0 and later of the Add-on Builder is also only compatible with Splunk version 8.0.0, which also runs on Python 3. See the Python 3 Migration manual.

Do not delete the $SPLUNK_HOME/etc/apps/splunk_app_addon-builder folder before upgrading the app. You need this folder to configure previous projects in the upgraded version of the Add-on Builder.

1. Download the Splunk Add-on Builder from Splunkbase.
2. Log into Splunk Web.
3. Click Manage Apps.
4. On the Apps page, click Install app from file.
5. Click Choose File and navigate to the Splunk Add-on Builder package file, then click Open.
6. Select Upgrade app.
7. Click Upload.
8. After upgrade, clear the browser cache and reload the page (CMD+shift+R on Mac OSX or CTRL+shift+R on Windows) to apply the new UI changes.
