I have another question on here that is almost exactly the same, but it had a lot more details and kind of went off track (and I never got my answer). So I'm trying again.
I know that this command works. When sent FROM my Samba4 ADC, the following command successfully replicates PDC -> ADC
sudo net rpc share migrate files sysvol \
-k --destination=ADCserverName.companyname.local \
-S PDCserverName.companyname.local --acls \
-U "companyname\\AdminAccountName"
What would the command be to replicate ADC -> PDC? Do I simply reverse the --destination and -S?
