Getting error when trying to upgrade from Splunk Light to Splunk Enterprise version 7 on school campus license server?

[glindley1122]

I originally installed Splunk Light on a server. After our campus acquired a Splunk enterprise license, I switched to the Splunk enterprise license by pointing to the campus license server.

Everything worked fine until I tried to upgrade to Splunk 7. When I try to do the upgrade, I get the error message:

"Splunk Light is already installed on this computer. Splunk Enterprise cannot be installed unless you first apply a Splunk Enterprise license."

You will need to uninstall the Splunk Light and install the splunk enterprise as a trial/free version, then after the first start, you just point to the master with the license.

To install 2 splunks, you will need to change the management port (8089) and the web port (8000).

Okay, the uninstall, re-install worked. After reading the docs on migrating splunk, I did the following:

1. stopped the splunk service
2. made a copy of the splunk install folder
3. uninstalled splunk 6.4
4. copied the splunk folder back
5. installed splunk 7.0.2

Can you uninstall splunk light first and then install Splunk Enterprise?

Wouldn't I still need a Splunk Enterprise license? I'm currently getting it from a license server, so don't have one on the server itself.

No you just point it to “your campus” license master.

I think it couldn't be possible to install both on a single server, but try installing Splunk enterprise on another directory on the same server. I am not sure about it but you can try.
If it still didn't work you only have one option that is to give the IP address instead of localhost in http://localhost:8000/en-US/app/launcher/home. Then you are able to access your campus Splunk enterprise with your campus Splunk credentials.
