cPanel IP migration

I had to switch the main IP address of a cPanel server. Basically you follow the IP Migration Wizard steps, but when I was done the A records for the main hostname were wrong (still having the old IP). If I went to edit the main DNS entry the IP was shown to be correct. What I had to do was to edit /var/cpanel/mainip

Also I searched in /etc and found one more refference to the old IP, I replaced that as well.
