Issue with fields_meta_data.id_c after upgrading to 11.0.3

Until a very recent release, the ID of the fields_meta_data table was 255 characters. The change to 36 characters occurs as part of the upgrade process. This is not caused by previous customization.

To add to Jeff Bickart's response, they didn't just change the size, they changed the ID.
It used to be a concatenation of module name and field name, and now it's a UUID, however they did not convert the old records to UUID, they have the old id format. 
So the table now has a mix of UUID and strings in the ID column, which looks a bit messy in my opinion.

Well, my case rep still won't help. Could one of you knowledgeable people let me know how I should rectify this? Should I just truncate the required number of characters to get it down to 36? Willl there be any consequences for doing so?

I did a quick grep on my SugarCRM code to see if the IDs were used anywhere, I did find them in the cache files but nowhere else. So you may be ok updating them.

If you are going to try it, I would suggest you make a backup of your code and DB first.

Then I would try to update those problematic records to have UUID() or truncate the id if you don't get any duplicates, and QRR. 
Then see what you can see... it's a bit of a gamble (hence the backup) but it might work...

Thank you. :) I will try.
