update a mame set?

[xokia]

I have a full merged set of 0.286 I'd like to update it to 0.287.

I downloaded the updated 0.287 CHD and Roms. I am trying to use clrmame 0.6.3 to update 0.286 to 0.287

First thing I did was download mame 0.287 and then creates a mame287.xml file

Then in the clrmame GUI for the source I use the mame287.xml file

Input paths:
Point to the 0287 CHD and Roms

output path:
I just create a directory called output_paths same with backup
I am thinking I should be pointing to the MAME 0.286 directory? (didnt want to screw up my directory if it failed) 
I assume I take the output_path files and just copy them into MAME 0.286 directory?

 

Now for the scanner side
for the source XML I choose the same 0.287.xml

Rom Paths:
I point the the MAME 0.286 ROM/CHD files
Backup_path same backup path that was used in rebuilder.

 

However rebuilder seems to run fine but when I run the scanner I get a bunch of issues. Anyone know how to do this successfully?
You would think with as long as MAME has been around it would be more user friendly or at least provide more meaningful prompts.
