The web site was already existed at the old hosting plan and the new site has been created at the new hosting site.
Since we have transferred all domain name and DNS setting, it is not still showing the new contents from new hosting site yet.
The DNS setting will be taken effect after 2-3 hours of routing time in most of normal case.
But you can still shorten this process for your development case by doing below steps;
1. go to the C:\Windows\System32\drivers\etc
2. copy hosts file to your desktop and open it from notpad
3. add below example line into the end of file and save it.(The example line should be modified to correct ip address and domain name
xxx.56.XXX.251 xxx.com www.xxx.com
4.replace the hosts file
