References to old IP addresses cannot be changed with IP Migration Wizard.

Symptoms

After the server IP is changed, the IP Migration Wizard is usually able to replace all references to the IP for the cPanel accounts and the Apache Vhosts in /etc/apache2/conf/httpd.conf file

Cause

Note: Make sure to replace $cpuser with the actual cPanel user 

However, due to leftover entries of the old IP at /var/cpanel/userdata/$cpuser folder for the specific cPanel user the IP Migration Wizard would not work and a manual change is required.

Resolution

To manually replace the old IP with the new one, please follow the steps below.

Note: Make sure to replace $OLD_IP and $NEW_IP with the appropriate values for your server.

1. Login to your server as root via SSH or use WHM Terminal

2. Confirm the old IP entries still exist with the following commands

   # grep -Ril $OLD_IP /etc

   # grep -Ril $OLD_IP  /var/cpanel/userdata/

   The commands will list all files which include your previous IP address. 

3. Execute the following command to replace them in 1 go for the specific cPanel user

   # sed -i 's/$OLD_IP/$NEW_IP/g' /var/cpanel/userdata/$cpuser/

   This can also be done in bulk for all accounts if necessary when running the command against the userdata folder itself.

   # sed -i 's/$OLD_IP/$NEW_IP/g' /var/cpanel/userdata/

4. Next and final step is to rebuild the secondary files that include those entries with the following command.

   # /scripts/updateuserdomains ; /scripts/updateuserdatacache ; /scripts/rebuildhttpdconf ; /scripts/restartsrv_httpd

CPANEL_INFO: If you have a lot of cPanel accounts and prefer to refresh the data for all of them, you can directly rebuild the userdata folder then execute step 4 from the above instructions.
