title: RPM+Yum: install two packages with the same name and different versions simultaneously
body: <p>For moderators: this question is about <strong>development</strong> of RPM based installer.</p>
  
  <p>I'm developing packaging system for our software. We've designed our update management so that when we want to move to the new major version, we change RPM package to install all files into another directory (with another suffix) and change the package version. We keep the same name for the package (like: a-package-1.0.0 --> a-package-2.0.0). We want to install the new package keeping the old one to make user able to continue work with the old version while he moving to the new one.</p>
  
  <p>So there is no file conflicts between our packages and RPM utility install them simultaneously without any issues (rpm -ivh ...). But Yum thinks that the new version is an update for the old one.</p>
  
  <p>Is there a way to produce such RPM packages to make 'yum install a-package-1.0.0 a-package-2.0.0' installing them both? Maybe some flag in the package have to be set? I've found nothing.</p>
