How to resolve KV port change error - upgrade from 6.1 to 6.2 on Ubuntu x64?

[r2r2]

Hello!
I upgraded splunk 6.1 to 6.2, tried to start new version but received a error:

Checking kvstore port [3433593128]: invalid; must be between 1 and 65535
Would you like to change ports? [y/n]: y
Enter a new kvstore port: 54321
Setting kvstore to port: 54321
Did not find "disabled" setting of "kvstore" stanza in server bundle.
Error changing port, exiting

Could you advice me anything, please?

It hadn`t worked because I copied old etc-folder.
I updated splunk again and now it works.
Thank you for your help!

How did you perform an upgrade to Splunk 6.2?
Could you do

head -1 $SPLUNK_HOME/etc/system/default/server.conf

This should tell that the version is 6.2.
Also please verify that server.conf has a default kvstore settings in it

$ tail -11 $SPLUNK_HOME/etc/system/default/server.conf
[kvstore]

disabled = false

port = 8191
replicaset = splunkrs
distributedLookupTimeout = 30
shutdownTimeout = 100
initAttempts = 300

dbPath = $SPLUNK_DB/kvstore
