I upgraded Elasticsearch from Version 6.2.1 to 6.3.0 using
yum upgrade /tmp/elasticsearch-6.3.0.rpm
after start I got error:

Did not find any hints to remove old x-pack before upgrade in the upgrade guide.
Any hints how to continue/fix?

Elastic 6.3 contains X-Pack by default. This worked for me.
`./elasticsearch-plugin remove x-pack`

removed content of /usr/share/elasticsearch before yum reinstall ...
to delete datasets from older releases.
