Migrate Account With No Downtime
How Can I Transfer Servers With No Downtime?
If you’re using a Cloud or Dedicated server and want to change servers, you can do the following to ensure there’s no downtime:
These steps are ONLY to be utilized once the content from the original server has been restored to the new server and confirmed working. These steps should be performed just before updating the nameservers for the transferred domain(s). If you have not transferred the content to the new server and you have WHM access on both, please refer to the following guide How to transfer/migrate an entire server to a new server guide.
Step 1: Log in to WHM on the original server
Step 2: Go to DNS Functions
Step 3: Go to Edit DNS Zone once you search for DNS in the search box in the upper left corner.
Step 4: Choose the right server/domain
Step 5: Click the Edit button
Step 6: Change the number in second column (probably currently 86400 or 14400) to 300
Step 7: Once the previously set TTL has expired and been changed, change the A Record IP to the new server IP
Step 8: If you no longer would like to manage your DNS Zone through WHM, you can change your Nameservers with your domain registrar at this stage so that your DNS is handled elsewhere. Before changing your domain’s Nameservers, it is important to confirm with your Authoritative Nameserver provider that your DNS Zone is configured properly and ready to be utilized.
Step 9: Repeat steps 1-7 for any additional domains that were transferred
