Q. How do I upgrade my CentOS Linux 5.0 dedicated server to WHM / cPanel edge release? A. You can upgrade to EDGE release from WHM manager. Please
note that Edge is the bleeding edge tree. While it has the newest features; It has undergone the
least amount of testing (if any). You generally shouldn't run this build unless you need a bug fix
or feature in it. Once an equivalent CURRENT or RELEASE build has been released, you should switch away from this.
Configure EDGE upgradea] Just login to WHM b] Look for Server Configuration c] Click on Update Config d] Set cPanel/WHM Updates option to Manual Updates Only (bleeding EDGE tree) e] Click on Save.
