As well as merging accounts we need conversations moved as well
Because a while ago MS forced people to log into their long time skype accounts using their MS accounts but managed to create a second account rather than just a new login to the existing account. Given this screwup and all the grief caused by users finding the wrong account the only "fix" is to have all the old users setup under the new Skype login. Unfortunately this means that you will be losing all the conversations under the original account. Over and above the ability to merge accounts we need all the conversations preserved in doing so!
