Hi, I am running ispconfig 2.2.21. When I installed ISPConfig, have not installed the mod_ssl (my mistake). One of my customers needs SSL. When I run YUM, YUM tell me that I must update httpd and distcache. These updates will have an impact on my customers? Also I'd like to update ISPConfig to version 2.2.29. What is the procedure and is there any problems or configurations that can change when i do this update? Thank you for your help!
