How to change Get(UUIDNumber) to Get(UUID) for parent Keys using Upgrade tool

[docasar]

Hi,

I am trying to work on a file that has predefined Get(UUIDNumber) for the parent keys, and I would like to change all those to Get(UUID). I wonder if I could use the Upgrade tool to just find and replace everywhere there it says Get(UUIDNumber) to Get(UUID) and also change the field type from Number to Text (this is because the file has more than 60 tables with their unique parent keys)

I saw the blogpost from Dbservices  but it was more as adding code not replacing code in FILE A with code from FILE B.

Thank you so much for any help!

Best regards,
