Server Upgrade Time!

So, it’s time to update my server! Currently, it’s hosted at DigitalOcean with an old Centos 6.5/2GB/40gb droplet. I pay a cool $20/month for my server for hosting, email, and about 10 other domains. It’s time to update!

So, I have to decide whether I will go with a Centos 7 or a Centos 8 image at $15/month. The only main difference is that I have to determine whether I need the updated Kernel and the additional updates and if my software/configs are easily portable to the new host.

I start my pre-migration experiment in 2 Virtual Machines using Oracle Virtuabox and the Centos7/Centos8 Minimal images. I get them installed, connected to the internet, yum update, and begin to install the necessary services that I’m currently running. I take a cool inventory of the versions I’m running, and the version that is currently available for install.

What’s currently offered for Centos Machines and Software

From the looks of what’s offered I quickly decide to go with Centos 8.

LET THE UPGRADE BEGIN!
