How to replace single row via with multiple row? Any dbGet solutions?

I am trying to find and replace all VIA5 that are single row with double row keeping the column of via same as before. One of those via has 1 row and 9 column, whose name is MT_M5_sym_2. I have to change it to 2 row and 9 column.

I was going to try this solution which I found in cadence support.

# Specify the via to replace with

setViaEdit -create_by Geometry -auto_snap 1 -cut_layer VIA5 -cols 9 -rows 2

# Query to determine via master cell name that was created:

dbGet head.vias.name EDI_*

 # Query  to verify MT_M5_sym_2 exist

dbGet head.vias.name  

 # Replace the via:
editChangeVia \
   -from {MT_M5_sym_2} \
   -to {EDI_*} \
   -area ...

 

But,  

encounter 120> dbGet head.vias.name EDI_*

0x0
It doesn't return any name. Any suggestions?


What other ways would you recommend to achieve this via replacment.  

Thanks a lot.
