title: How to install two different versions of same rpm and make them work parallely
body: <p>Currently I am trying to install a rpm secured_soft_2.0.0.rpm and i am 
  unable to install it as we already have secured_soft_1.3.0 installed.  </p>
  
  <p>Requirement is that we need to have both the versions installed.  </p>
  
  <p>Complexities :</p>
  
  <p>These package inturn have dependent rpm's (lot of them ) and all these
  interdependent rpm's also have versions
  ex: secured_soft_1.3.0 works only with packages which are of version 1.3, 
  and secured_soft_2.0.0.rpm work only with dependecies of version 2.0 only.
  So all these dependencies also need to be reinstalled and even these 
  dependenies should be parallely installed, without deleting old.</p>
  
  <p>Finally , both these versions contain shared libraries and these shared 
  lib's do not have version numbers in their name.</p>
  
  <pre><code>#rpm -ivh secured_soft_2.0.0.rpm
  error: Failed dependencies: 
  init-class &gt;= 1.4.17.1-1 is needed by secured_soft_2.0.0.rpm    
  init-connection-interface &gt;= 2.0.11.0 is needed by secured_soft_2.0.0.rpm  
  init-logger &gt;= 2.0.11.0 is needed by secured_soft_2.0.0.rpm  
  init-security &gt;= 2.0.11.0 is needed by secured_soft_2.0.0.rpm  
  </code></pre>
  
  <p>As i have specified we already have secured_soft_1.3.0.rpm installed and
  above dependencies are also available but of different version.
  So we need the to install above dependencies and also need the old version's 
  of dependencies for the old rpm's to work </p>
  
  <p>ex : secured_soft_2.0.0.rpm has libArt.so libSec.so and so on 
  which are copied to /usr/lib</p>
  
  <p>Similarly secured_soft_1.3.0.rpm also has libArt.so libSec.so and so on
  which are already available in /usr/lib</p>
  
  <p>I tried to rename the so's but still iam not able to install.</p>
  
  <p>Is it possible to change the location for these so's and get the things done
  Is there any way we can do it.</p>
  
  <p>At the moment, iam stuck here and would need advice on this
  Appreciate any help on this.</p>
