different SharePoint server with same configuration and dBs can share the same workflows?

I have two SharePoint servers in my company in which one is production and other is DR. and also, the replication between both servers DB's. both servers have same configuration and same data. I have developed few workflows in Production server. Please let me know in the case if production server will collapse and I moved to DR then same workflows which I developed for Production will also work with DR automatically or need to develop new one for DR.
