Bluehost VPS: Upgrade CentOS from version 6 to version 7

I have used Bluehost's VPS plan more than 6 years. I recently upgraded the CentOS version from 6 to 7. If the version of CentOS is 6, you can upgrade it to version 7 with the help of Bluehost.

I got a notification email from cPanel:

Newer releases of cPanel & WHM are not compatible with your operating system. Upgrade your OS, or use the Update Preferences screen to select a Long-Term Support release for use with your OS. Starting with version 88, cPanel & WHM supports 64-bit versions of CentOS 7+, Red Hat Enterprise Linux 7+, and CloudLinux® 6+ only. Please see our OS End of Life policy for more information.

I contacted Bluehost and was told that the OS needed to be upgraded.

You have to check the following details:

  1. All content is deleted and replaced with default files, including mail, site files, installations database, and any changes made in root.
  2. DNS entries are removed and recreated with default values. This removes all custom DNS Changes.
  3. Add-ons/parked/sub domains and their related folders and files are removed.
  4. All email and FTP accounts are deleted.
  5. The username stays the same.
  6. The account password stays the same.
  7. All other user accounts are removed from the hosting instance and will need to be recreated.
  8. Sudo access will need to be reconfigured.
  9. Any SSL certificates installed will be removed. (You would need to backup)
  10. All cPanel backups on this hosting instance will be deleted.
  11. This will take a minimum of 24 hours to complete.
  12. Backups would be removed from the hosting account. Please download any files before we start the re-image

I downloaded cPanel backup and then requested the OS upgrade. It took about 2 days to finish the upgrade process.

If you sign up for Bluehost webhosting service by clicking on this referral link, I will get some commission. However, I do not recommend a specific web-hosting service just for commission; I have been using Bluehost, Siteground and other webhosting services for years. Most especially, you will be able to use Bluehost's web hosting service starting from as low as USD2.75/month (with 1USD off per month).
