Changing webserver CentOS 6

I decided to change my webserver (dedicated) from a hosting provider to another. Both servers are on Centos 6 Whats needed: 1. add the IPs given by the new hosting company to the network interface as they just give me a block of IP 2. uninstall the free trial cpanel (given by the hosting company automatically) and install virtualmin/webmin. 3. Install the fallowing modules as some of the websites are videostreaming sites: PHP CLI,MEncoder,MPlayer,FFMpeg,FLVTool2,Mediainfo,MP4Box,NeroAacEnc 4. assign the domains to ips, create their ns, ftp , ssh, mysql users (probably through the webmin) 5. transfer all the websites and databases from old server to new server
