Error when upgrading Splunk Enterprise from 9.0. to 9.2.1

[SahilGupta942]

Hello Team,

I had followed steps mentioned in below page for migration to Splunk Enterprise version 9.2.1:

Upgrade to version 9.2 on UNIX - Splunk Documentation

I receive below error on running start command. Due to this error, I am unable to complete the migration on Splunk indexer machine.

Warning: cannot create "/data/splunk/index_data"
Creating: /data/splunk/index_data
ERROR while running renew-certs migration.

i have the same situation when i try to migration my splunk from old server RHEL6.9 to new RHEL8.8

i did rsync complete and created user splunk as new server

ran rpm -i of same version to the new server and shows complete with zero error, however when i went to /opt/splunk/bin and ./splunk start it shows same error like you.

May i know any update of yours, did you fixed ?

This looks like looks like filesystem permissions. 

The splunk paths are normally based on the splunk account user permissions 
example 
sudo chown -R splunk:splunk <YOUR DATA PATH>

Find out what account Splunk was running under.

Or - if the permissions look right - a SELinux mislabeling issue.
