PRD refresh to DEV

PRD refresh to DEV

I have a Zoho Creator App which I have been using for years.


It's PRD and I never had a DEV version of it.


Now I want to create a clone of PRD  and call the clone DEV, in another Zoho account.


In the future all development and coding will be done in DEV, and from DEV I will push incremental changes to PRD.... how this can be done ?  this is in a retroactive fashion... usually u create a DEV then do a copy from DEV to PRD and call it system copy... thanks!!!!
