How similar are the 131A and the 132A ? Is it possible to upgrade a 131  
into  132 ?
Interesting question!
I suspect not, not in any straightforward fashion anyway, but I'm sure  
others would know better than me.
>From a quick look at the component level service manuals the  hardware does 
seem to be very similar, although just how similar  would need a bit more 
detailed investigation, but then there's no guarantee the  FPGA programming 
would be the same.
I suppose an interesting experiment might be to drop a set of 53132A  
firmware ROMs into a 53131A, not something I've tried, but I wouldn't be at  all 
surprised if they weren't recognised.
