No i used the same installer bat files I always do. Although my local copy crashed when running it the servers updated fine...

For the pub I had to delete the installer record file and then it worked. This update seemed to have a buggy roll out.

as for old folder issues. All of the ibis servers were recreated from scratch on fresh install post update so that I would not need to worry about having any old file structure around or wasting HDD space with useless folders and files.
