I have two SQL Server 2012 machines in two different domains. Server A can communicate with Server B over a VPN. This VPN is one way, that is port 1433 is open from server A to Server B but not the other way.
I have tried to set up Transactional Replication with Server A as the Distributor/Publisher. This seems to work but when I go to Server B to create the Subscriber, I get the following error message:
"The selected Subscriber does not satisfy the minimum version compatibility level of the selected publication."
Server A is a SQL 2008 Express updated to SQL 2012 Developer. Server B is SQL 2016 Developer. I use SSMS version 2014 on both servers. I have set the database Compatibility Level to 110 for both the source and target databases.
I thought this might be due to the one-way VPN. So I also tried Log Shipping. This does not seem to work either. Are my problems due to this one-way VPN? If so, I just want to get a copy of the database on Server A copied to server B. I don't want to do this manually so is there another way I should look at?
Thanks.
