Is there any way to upgrade or switch from ISPConfig 2 to 3 withow have to reinstall the whole server? thanks
No. You have to reinstall. As I mentioned in your other tread, please search for a topic before you post a new thread
Do not feel bad because you cannot find a post on this. I have searched all over the forum. I just hate it when people take the time to post "search the forum". If they know it is out there then it would be nice to post that thread link. It is like looking in the pone book for some thing and seeing look somewhere else for this. Just a thought.
Everything that is to say about this topic is in the thread: "No. You have to reinstall.". And to the other part, you see that I was referring not just to this one post of the user.... "....As I mentioned in your other tread...."
