Renaming a universal security group

Hi

I do have a group universal security group in our AD and we have 100 staff within this group.

Group name is called as :
Group name (pre-Windows 2000):CLV Staff
Email is: CLVStaff@myorg.com

It is possible to change the group name from : CLV Staff to All CLV Staff
Email to :AllCLVStaff@myorg.com

If i make these changes , will this cause problem to users on the network ?

Any help much appreciated.
Thanks
