How To Transfer a Cpanel Account To a Different (WHM-Based) Server
This article assumes that you’ve got two servers: one with a cpanel account (server X, with IP X.X.X.X), and another server that you’d like to transfer to (server Y, with IP Y.Y.Y.Y).
We’re also going to transfer the nameservers from server X to server Y.
DNS Setup:
- Add A records to server X, registering the hostname of server Y.
- Add A records to server X, registering “ns1” and “ns2”, pointing to server Y.
Full Cpanel Backup & Transfer:
- Login to the cpanel account of server X.
- Create a full backup of the account and wait for it to finish (may take some time, depending upon the size of the account).
- Rsync the full backup (tar.gz) to the /home/ directory on server Y.
- Once the backup file is transferred, login to WHM on server Y, and initiate a full restore. If the backup file is in the /home/ directory, WHM should detect it, and allow you to choose an account to restore it too.
Prepare to Cutover the Nameservers:
- Login to the WHM account of server Y.
- Use the “Edit DNS Zone” tool to examine the dns records that have been imported from server X. The main A record IP address for all domains should have been changed to Y.Y.Y.Y during the restore. Ensure things look good and make sense.
- With WHM, go to ‘WHM > Basic cPanel/WHM Setup” and scroll to the bottom. Setup the new nameserver IP’s here.

- Now we should be ready to change the nameservers. Login to the domain registrar, and change the nameservers from ns1.olddomain.com and ns2.olddomain.com, to ns1.newdomain.com and ns2.newdomain.com.
- Clear your dns cache (on Windows command line, that’s “ipconfig /flushdns”).
- Watch for the new changes in the dns information, with nslookup.
