The VeSys Classic user fields should get mapped to the CHS Capital Library user fields (Extra details tab).
Thanks alot for you time and inputs.
I want to map one of my user field to inbuilt property field of CHS.
something like swapping the Vesys User Field with CHS Property field while importing a database.
This could be done by editing the Library XML file, however I would suggest you use a qualified consultant to do that transformation of the XML.
