When migrating Splunk and upgrading from 7.0.5 to 7.1.2, why did it install to a different Splunk home directory?

[xindeNokia]

I have manually migrated a previous instance to a new box. Migration was successful.
Migration steps are as follows:

1. copied all indexers and all configs under $splunkHome$ to the new box
2. rpm -i 7.0.5 Splunk software
3. we changed our Splunk home dir from /opt/splunk to /splunkhome/splunk
4. I have to change etc/splunk-launch.conf to the new home dir - splunk can come up.

But, when I try to upgrade Splunk by using command rpm -U splunk-7.1.2-software , I found Splunk did an install under /opt and did not do any upgrade under /splunkhome .

Is this expected? Is there a way to fix it?

Thanks in advance

Just used a --prefix and direct upgrade works.

I tried remove both version and restore again.

Both installation all point to /opt instead of /splunkhome even I install the software under /splunkhome.
is there any environment parameter I need to set?

Why do not you run the command "rpm -U splunk-7.1.2-software" first?
1. upgrade splunk by suing command rpm -U splunk-7.1.2-software
2. copied all indexers and all configs under $splunkHome$ to the new box
3. rpm -i 7.0.5 splunk software
4.change etc/splunk-launch.conf to the new home dir - splunk can come up

You use file .rpm is the default /opt/splunk. But you can use file .tar
tar xzf splunk-7.x.x-.tgz -C /splunk/parent/directory
