Driveshaft CV Joint Boot Replacement

I've noticed a small nick on the outer cv joint boot of one of the driveshafts so need to replace it. I've ordered a new boot for it but am wondering how best to get the new one on. I'm not sure if the one I've ordered is a 'stretchy' version that can be slid on over a cone or if I need to get the joint apart.

Anyone have experience of changing the cv boot? Did you take the joint off the shaft or use the 'cone' tool?

Thanks
