When I must to change to dedicated server?

When CPU and memory usage are very high?

(my hard disc and transference usage is very high, but it is included in basic hosting... or not?)

Hi Salva85,

It is not hard to manage dedicated server without a lot of experience, if you purchase control panel for it. Since you have experience with cPanel on the shared plan, I would recommend purchasing this control panel for your dedicated server as well. cPanel gets installed on our dedicated servers with similar setup like our shared ones have.

As for when to switch to the dedicated server, there can be two reasons. First is you need some component that can't be installed on the shared server. Second is resource consumption by your site that overgrows the allowed limits for shared plan. The most important limits are cpu, memory and mysql connection utilization. Unfortunately, you don't have access to the resource stats for your site and you can ask the support to provide them from time to time to see, if you are near to or in the the red line. However, my recommendation would be upgrading to the dedicated server before when you are expecting traffic and client amounts increase to avoid possible downtime or hurry with site switch to the new server.

Please advise, if you have any further questions.

You might also get emails from your host telling you that you should upgrade to a dedicated server.  If they notice your website causing too much strain on the server, they will recommend you either upgrade to dedicated or remove a script that may be causing the large server usage.
