I've been a user of the VMware products for almost 10 years including using Fusion 4-10. I am currently using Fusion 10 Pro, the latest for High Sierra. I downloaded a copy of Parallels yesterday (20-Feb) and all I can say is my sluggish Fusion is operating like new with Parallels. It feels like its a natively built machine, but its actually a conversion from Fusion to Parallels using the converter.
Like everyone here, do you offer discounts from Fusion to Parallels like you have in the past? I am not looking for the subscription based one and maybe at this point don't need the professional version if the desktop version seems to have everything I need.
