KDE in SuSE 7.1

A question to one of the gentlemen from SuSE, please! I am looking forward to receiving my SuSE 7.1 subscription update. When I have installed it as an upgrade to 7.0, (not a new installation) I only want to have the new KDE, and not the older versions which are with SuSE 7.0, on my machine. Will installing 7.1 as an upgrade, overwrite the existing versions of KDE, or should I delete them before installing the new SuSE? I would like to get that point sorted, please. Many thanks Keith Powell keithp@g4jvx.screaming.net
