I am running CentOS 7 on a HDD disk drive.
For some reasons, I want move the OS image on HDD to a new SSD.
(Using SSD as data storage is not an option, for some reasons)
How can I copy the existing installed CentOS 7 image without loss to a new SSD drive?
It seems that someone uses dd command to copy the device data, but I guess there must be better and reliable way to achieve it.
How can I do this?
// SSD size is bigger than HDD's.
I have 25 machines to work on. If I can do copying the OS image on commands, it would be way better
