I need help to upgrade Oracle Linux Server 6.4 to 7.
cat /etc/*-release
Oracle Linux Server release 6.4
Red Hat Enterprise Linux Server release 6.4 (Santiago)
Oracle Linux Server release 6.4
When I try update I got
[root@serv rpm]# yum update
Loaded plugins: security
https://yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/x86_64/repodata/repomd.xml: [Errno 14] problem making ssl connection
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: ol6_UEK_latest. Please verify its path and try again
The same error in try install requirment tools
[root@serv rpm]# yum install redhat-upgrade-tool preupgrade-assistant preupgrade-assistant-el6toel7 preupgrade-assistant-el6toel7-data-0 preupgrade-assistant-tools preupgrade-assistant-ui openscap

I know the problem is due to Oracle disabling the old TLS. But how to fix the problem?
