Your local respositories should be visible in ePO so it replicates the files to it. As they are visible to it you can select in your Agent config to install from a certain repository. As there are a lot of sites I hope you can select subnet distance or ping. So that the agent always uses the local server to the remote site.
If your replication is configured adequately, you should place 8.5 in your main ePo and it should just replicate to the 50 local servers. Then you change the deployment task and all clients connect to that local server and upgrade.
If not, a DoS will happen, to mitigate this you can select big randomization times. So that not all start at the same time.
