Blueberry Bushes

Hello fellow gardeners.

I have 4 blueberry bushes in containers. All are doing really well, plenty of foilage, plenty of flowers.

My question is this.
I've noticed that a couple of the bushes look like they are getting rather big for the container they are in. I do wish to move them to a larger container. I am just wondering if Blueberry bushes cope with a move to another container?
I do not want to kill them off obviously. I just want to make sure it will be fine to repot them.

Thanks in advance.

 

What do you mean the normal care with the roots??
