Let's say that you lease 10 dedicated servers from the same company... You are now making decent money for yourself and decide that you would like to start your own NOCC. The place you are leasing the servers is several thousand miles away from your location... How would you go about doing this? Would you buy the servers from the leasors, but if you did that then the IPs are going to be different, that would be a mess. Would you just go and buy 10 servers, install the same CP and pay someone to move every site, one by one... even then though the DNS for every site would be different. There doesn't seem to be any way of doing it, without really interfering with the customers uptime.

I know this is hypothetical but you wouldn't want to start a NOC just because you had 10 servers and were making a bit of a profit. Data Centers cost millions to build... you've got to think about the facility, fire protection, security, raised flooring for cabling, rack systems, backup systems and generators, monitoring, employees, etc.

I wouldn't think about it unless you had a few hundred or even a thousand servers unless you could land a good contract proviing colo services.

Anyway, there are easier ways to get all the accounts off one server and onto another than transfering them one by one. It's not easy by any means though. My suggestion would be to build the NOC and get it up and running, putting all new accounts there. Then slowly migrate your old servers there on a one-by-one basis.

How about getting a rack and coloing your own servers there? That's 1 step up from straight leasing, but much more affordable than building your own infrastructure. :)
