title: Is it possible to use diff and patch tools to achieve the desired result?
body: <p>I have a dir D-1.0.3 and D-1.0.5 with files A and B (and other subdirectories and files within D-x.x.x) with the following version tree of file A and B (alike in terms of versioning, also the other subdirs and files)</p>
  
  <p>1.0.3 - 1.0.5</p>
  
  <p>|</p>
  
  <p>1.0.3.1 (head)</p>
  
  <p>I would like to apply changes from 1.0.5 to 1.0.3.1 using diff and patch tool as i don't have access to git or svn tools associated to the files.</p>
  
  <p>Is this possible using the unified diff format (or whatever)?How can I achieve that if possible (the command set i need to execute)?</p>
  
  <p>I have checked that there is no adds, deletes or rename of the filename associated to the changes.</p>
  
  <p>Many thanks!</p>
