ABSTRACT:
A host migration system having an first server, a second server and a relay server is provided. The first server is currently hosting an internet service having a predetermined domain name. The first server has a first IP address. The second server has a second IP address and the relay server has a third IP address. The first data packet of a request from users is redirected to the first server from the third server and a second data packet of the request is redirected to the second server from the third server. The data packet redirection may occur as an IP address mapped to the domain name is changed from the first IP address to the second IP address via the third IP address. The host migration system may provide substantially minimized downtime and data loss and corruption may be prevented.
