Servo motors control using LinuxCNC

Hi folks, I have a stepper motor-based CNC and I would like to change the motors to servos, I need guidance for it, how can I configure the motors such as stepper motors what drives shall I use, and so on. 
Thanks

We need more info. Especially about the drives. If the drives you use take step/dir then almost nothing will change.

If the drives take Modbis or EtherCAT then a lot will change. If the drives take analogue velocity commands then you will need new interface hardware.
