Replication supports the following features on Availability groups:
A publication database can be part of an availability group. The publisher instances must share a common distributor. Transaction, merge, and snapshot replication are supported.
In an AlwaysOn Availability Group an AlwaysOn secondary cannot be a publisher. Republishing is not supported when replication is combined with AlwaysOn.
Four new stored procedures provide replication support for AlwaysOn.
· sp_redirect_publisher (Transact-SQL)
· sp_get_redirected_publisher (Transact-SQL)
· sp_validate_redirected_publisher (Transact-SQL)
· sp_validate_replica_hosts_as_publishers (Transact-SQL)
