We have one central server 2012 standard version, whith 2 replications to 22 local servers: all tables of 1 schema is replicated with a transactional replication, another scvhema is replicated using merge replication. We want to upgrade to 2019, which means we would need to upgrade the SQL park in 1 big push, because 2019 cannot be published to 2012. My question: if we run run the database that needs to be replicated in compatibilty mode 2016, can we than publish to 2012 subscriptors? This means we could upgrade per cluster instead of doing all in one big push.
