I am upgrading AX2012 R2 to CU7 and trying to use the new Merge Code Automatically feature introduced in the update. We have quite a few customizations on the VAR layer and I'm running the Merge job on it.
The problem I have is the merge takes ridiculously long time to process - the last time I checked the progress bar estimated 187 hours remaining and it was stuck on the same method for more than an hour at that point.
Using CTRL+BREAK to get into debugger revealed that 99% of the time is taken by method \Classes\SysDiffUtil\generateMatrix, which executes >1M loops for each customized method.
Has anyone faced the same issue or am I overlooking something?
