The results of a merge are normally shown on the Results page.  That page is an HTM page in the logs folder that can be reviews later.  Know Bug:  The HTM file may not be displayed after a large merge.  The XML page is not properly processed to build the HTM results page.  The merge was completed but the results were not displayed.  This was due to a problem with the progress bar being displayed and was fixed in 14.3.   Below is what is NOT displayed on some large imports on fast machines.

Status: Fixed
