Hello experts,

I'm a bit of a learner here, so thanks ahead for your patience.

Unfortunately I started using Zoho CRM  without an 'Industry' field setup in my Deals module.
I do have that field in Leads and in Accounts.

I have now finally added the 'Industry' field into my Deals module and this should now work as I wanted through future input/conversion mapping process.

However, the result is that most of my existing deals now have the 'Industry' field as blank.
Conversion mapping of course does not work backwards and changes do not update throughout the mapped modules.

How can I get my pre-existing 'Industry' field information from my Accounts module into my new 'Industry' field in my Deals module?
And also perhaps make sure that any changes in any module reflect through all of 'Industry' field.

Thanks
