we are planning on a publishing functionality for our SP2013 site. (please note that we are not using the cross-site publishing feature, but ideally we are implementing similar concept)
There are 2 farms. The first farm has 2 site collections (one for each department).
The 2nd farm has 2 site collection as well (one for each department).
Managers upload documents into a document library on FARM1 on any one of the departments site collection. Once they are published we want to upload them into a document library on FARM2 on the respective site collection. What is the best practice to perform this?
