Moving well established Euonymus

Hi Everyone. Hope you are all well and finally enjoying some good gardening weather.
Now on to my question. I have about 5 well established Euonymus bushes. They were planted
as a wind break and do their job well. However, I have created a new seating area and I want to move them about a metre backwards so we still get the privacy/wind break but can use the rest of the bed for flowers which we will be able to see.
Is there any time I should/shouldn't move them and do you think I am likely to lose them if I do.
Any advice greatly appreciated.
