Splunk's documentation has guides for exactly this:

• https://docs.splunk.com/Documentation/Forwarder/8.0.4/Forwarder/Upgradethenixuniversalforwarder
• https://docs.splunk.com/Documentation/Forwarder/8.0.4/Forwarder/UpgradetheWindowsuniversalforwarder

Hi @uagraw01 ,

at first you have to define the version to upgrade remembering that the UFs' version must be the same or lower than the Indexers' version.

Splunk doesn't give a tool to upgrade UFs so you can use your Software Distribution tool or someone available on internet (Asnsible, etc...).

If you haven't none, you can use a script that you can find in community answers.

Recently there are two apps to upgrade UFs but I didn't still used:

https://splunkbase.splunk.com/app/5004/

Ciao.

@gcusello I want to upgrade this from 6.5.5 to 7.2 ? You have any documented steps rather than Splunk docs. If you have please share it with me.

Hi @uagraw01 ,

no I haven't additional documentation, I usually use docs and eventually Community Answers.

If you have to upgrade from 6.5.5 to 7.2.x you shouldn't have a special migration path, but, check if you can upgrade to an higher version so as not to be forced to retry the operation in a short time (we're at 8.0.4 version).

If you have to upgrade from 6.5.5 to 8.x you have to follow an upgrade path (https://docs.splunk.com/Documentation/Splunk/8.0.4/Installation/HowtoupgradeSplunk).

Ciao.
