I am using Cpanel/WHM on a dual opteron 248 with 2G server. Apache 1.3.33, PHP 4.4.4, Mysql 4.0.27, I am expecting to change apache to LSWS. May I know 1) can I install free edition on my server with dual opteron CPU? will it be working? 2) based on the post at http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:apache:cpanel is there anything need to be done for PHP? 3) is there extra anything I have to do? I don't want to crash my existing sites on my server. 4) can I smoothly upgrade to your enterprise edition later? Thanks.
