CentOS7-to-EL9

Upgrade CentOS 7 systems to Enterprise Linux 9 (EL9)

Check CPU Compatibility

Upgrading from CentOS 7 to EL9 requires ensuring that the underlying hardware supports the necessary CPU features. Particularly x86-64-v2 architecture support.

How it Works

The script reads the /proc/cpuinfo file to detect the CPU features of the system.

Usage

chmod +x check_cpu.sh
./check_cpu.sh
