I have a very large existing set of tables being replicated (transactional) between two servers over a dedicated VPN connection. I need to add a new table. Reloading all the tables is not an option.
I thought that by simply adding the new articles to the publication it would replicate them across, but that didn’t work. Of course, something needs to tell the subscriber about the new articles. I then chose Generate Snapshot on the publisher, but I couldn’t tell what it was doing (maybe scripting out all the data?) so I shut it down. Maybe I should have let it run? I’m not sure.
So how do I safely add the new articles to the existing subscription?
I found the answer. The problem is that I did not use the initial snapshot to initialize the subscriber in the first place. I used a different method (the backup and restore method), which means I have to manually transfer the schema and data before starting up the transactional replication process.
