I'm trying to upgrade from 6.2 to 6.4 on a linux server and hitting some pain points. Can someone tell me what I'm doing wrong here?
**Attempt 1**
1) I backed up my `Splunk_Home` folder (Known as 'splunk') on my local drive
2) I renamed the splunk folder to 'splunkOLD' on that dev server
3) I downloaded this .rpm file `splunk-6.4.0-f2c836328108-linux-2.6-x86_64.rpm`
4) I ran this command `rpm -U splunk-6.4.0-f2c836328108-linux-2.6-x86_64.rpm`
5) Accepted the license agreement
6) Installed a fresh copy of Splunk which did not retain the user accounts and data, or my conf files.. The UI was available, but I only had access to the admin/changeme creds
**Attempt 2**
1) `Splunk_Home` folder is still backed up on my local drive
2) I rename that `splunkOLD` folder back to its original name `splunk`
3) I ran this command `rpm -U splunk-6.4.0-f2c836328108-linux-2.6-x86_64.rpm`
4) It says...
warning: splunk-6.4.0-f2c836328108-linux-2.6-x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID xxxxxxxx: NOKEY
package splunk-6.4.0-f2c836328108.x86_64 is already installed
