The logging action for the process outlined at Re-attempting the migration – for content in 'unmigrated-wiki-markup' macro is not as helpful as it could be. Currently, IF debug logging is enabled we receive a list of the macros that we failed on. However, we are not told how many times each occurs or what page they are on. This information would be very helpful especially for Macros that are never going to be upgraded to the 4.0 series which need to be removed altogether.
