I am not sure if this is where i need to post this question. I have ispconfig installed on my server, it works great. but because it lacks the billing feature, i am going to have to upgrade to 42go ISP-Manager. I sent the form for the free trial download but after i submit the form, it just takes me to the home page, there is no confirmation, that was four days ago, so i am asuming they didn't get my request. anyway. hopefuly someone will reply to me. my concern is that i have several site on the current ispcofig, once i get the 42go ISP-Manager software, will i have to do a fresh install, or can i just upgrade to 42go ISP-Manager on the current ispconfig server keeping all the configuration? Thanks in advance?
