I recently went with WattaServer to move my CPanel server in an effort to cut costs from the CPanel rate hike. I put their support staff to the test with their free migration. I have almost 300 cpanel accounts that needed migration to the new server, many with custom configs. I was impressed when I received an email notification 24 hours later that the migration was complete and what the next steps were, to update my registrar DNS with the new server IPs. I've been spot checking the accounts for over a week now to make sure everything is correct and working, I have yet to find any issues. I am in disbelief that it went so smoothly and quick. I felt compelled to share my experience.
