KDE3 Beta2/SuSE7.3

Will the installation of the beta rpms from the SuSE ftp site allow this installation installation to coexist with a previous KDE 2.2.2 installation or should KDE 3 beta2 be installed from source to facilitate that??? I would like to be able to run either at will until I'm confident I can let KDE2.2.2 go. Thank You, Anthony
