How install a new package without remove old package?

Dear all,

I would like to install a new version of package without remove old version on Centos and vice versa.

Please give me advice!

thanks much,

Well, if you download the .rpm package and install via "rpm -i package" instead of -U (upgrade) the old one should be kept, in case you want to deinstall the latest.

rpm  -ivh packages
