Disabling TLS1.0 and TLS1.1 will affect during upgrade of gitalb?

Hello Team,

       We are planning to disable TLS1.0 and TLS1.1 on gitlab-ce 9.2.5 due to security issue. After we disable it , will it cause any issue for gitlab activity?  

We have planned to upgrade current gitlab-ce 9.2.5 version to 10.5.8. The changes on TLS will cause any issue during upgrade? Do we need to take care of any precaution before upgrade?
