Need to move server during indexing process

Hi guys.. I'm your worst (nominatim) nightmare.. it is the fifth or sixth question I have posted on this argument.

I hope this is the last one.. The process is at rank30 and 60 hours still remaining. But the company is moving to another office and we need to move the server. We have a big power supply but I doesn't know if the process need internet to downloading something while processing rank30. Does it need it?? Can I move the server with adeguate power supply and no net??

Thank you a lot Giacomo
