splunk enterprise Upgrade from 5.0.5 to 6.1.1 failing

[spsrasru]

I'm upgrading splunk indexer server from 5.0.5 to 6.1.1 on Windows Server 2012.

I run the installer as a administrator but failed with errors.

this is the error i get from installation wizard:
Splunk installer was unable to launch splunk's First Time Run.
Error Code: 1

this is the error from migration log:
ERROR while running rename-cluster-app migration

Any help regarding this would be greatly appreciated!

Thanks,
Sam

Try to delete /Applications/splunk directory and installing it.

Able to upgrade successfully once i delete the splunkd and splunkweb Service.

Run these commands using powershell:

((Get-WmiObject -class win32_service -filter "name = 'splunkweb'").stopService()
(Get-WmiObject -class win32_service -filter "name = 'splunkd'").stopService()
cmd
sc delete splunkd
sc delete splunkweb
exit

I tried to find the solution for your problem but there was no answer for it.
So I was wondering re-installing the splunk might help..

Sorry if i misunderstood....You mean $SLUNK_HOME/etc/apps/splunk ? how this is related ?
