How to Migrate From CentOS 8 to RockyLinux 8.4

After #RedHat shifted its focus from CentOS 8 to CentOS Stream 8, Mr.Gregory Kurtzer, the original founder of CentOS, has started to develop another rebuild of RHEL, named Rocky Linux.
Rocky Linux is a community enterprise operating system designed to be 100% compatible with RedHat Enterprise Linux.
In this guide, we will cover how to migrate from #CentOS 8 to #Rocky_Linux 8 step by step. For the demonstration purpose, I have one CentOS 8 system installed.
Note: Before Upgrade, please make sure you take the backup of applications and if possible, take the snapshot of complete CentOS 8 system. There could be scenarios that after upgrade application stop working. So, in such scenarios your application can be restored from backup.
