title: How exactly do you reintegrate a branch into a parent branch using TortoiseSVN?
body: <p>So, I had this problem again and decided to hear from the experts(please only those who know what they are talking of please).</p>
  
  <p>I created a branch(DUMMY-BRANCH) from another branch(called UAT_BRANCH and this main is sort of a main branch for test releases). I made changes in DUMMY-BRANCH and tested those changes until I was satisfied with those changes. Then it came time to merge my changes back to the main branch, in this case UAT_BRANCH, and I went ahead and opened up TortoiseSVN to get this done.  I opened up the online manual at <a href="http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-merge.html" rel="nofollow">MERGE TWO DIFFERENT TREES</a> , and proceeded to yet again try my hand at getting this merging thing right. I specified UAT_BRANCH as the FROM(start URL) and DUMMY-BRANCH as the TO(End URL). I tested the merge  and then did the actual merge in the end. When I refreshed UAT_BRANCH and checked to see if the changes in my branch had been re-integrated, I found it was not. Now subsequent attempts at switching the FROM AND TO urls yielded no result, probably cause the damage has been done or something(I figure reintegration had already taken place and there was no undoing it).</p>
  
  <p>What I would like is some clear explanation of what I did wrong in this case please and how to actually do a merge in SVN or in fact tortoiseSVN. Thanks in advance. </p>
