Just helped to create a similar sync setup yesterday for a client of 100k acres (super happy, already created Workplans with both seeding and fertilizing using different maps). 

Please check it out: 
geopard.tech/johndeere

Steps to make a sync:
1) Create free geopard account (then you can choose between pay-as-you-go or subscription), 250 ac free trial
2) Connect your jd ops center account inside geopard
3) Sync organizations / selected fields
4) Setup automated data sync in both ways (from ops center to geopard - as-applied/harvesting; from geopard to ops center - Rx, Workplans, map layers like soil, topography, satellite imagery)

Let me know if any questions!
