Do we need to disable Kerberos and TLS before upgrading cloudera manager and cdh services.
I am planing to upgrade cloudera manager 5.9 to 5.11.2 but cloudera hadoop cluster is kerberos enabled and TLS level 3 enabled.
Thanks.

No, enabled security settings shouldn't make any difference to an upgrade.
If you look at Upgrading from CDH 5.4.0 or Higher to the Latest Release nothing is mentioned about Kerberos or TLS.

Yeah, cloudera didn't mention about disabling security. – Michael Dec 20 '17 at 01:00

Cloudera docs _do_ mention that you **cannot disable** Kerberos once it's enabled. Or rather, it's you and the multiple configuration files without support. Good luck. – Samson Scharfrichter Dec 20 '17 at 08:22

I upgraded CDH few days back to latest version. I disabled security and enabled after upgradation. We can also do it without disabling the security but might face issues.
