We recommend attempting an upgrade of a replica of your replication topology in a test environment before running the upgrade on the actual production environment. Upgrading a replication topology is a multi-step process.

However, the in-place upgrade process should also be used when patching SQL Server with a service pack or cumulative update as well. The majority of this article is scoped towards upgrading the version of SQL Server.

This phased approach helps control downtime and minimize the impact to a certain extent for the business dependent on replication. For environments running Always On Availability Groups or Failover Cluster Instances, an in-place upgrade is combined with a rolling upgrade to minimize downtime.ДЄ common approach that has been adopted for side-by-side upgrades of replication topologies is to move publisher-subscriber pairs in parts to the new side-by-side environment as opposed to a movement of the entire topology. In-place upgrade: Allow the SQL Server installation media to upgrade the existing SQL Server installation by replacing the SQL Server bits, and upgrading the database objects.Side-by-side: Deploy a parallel environment and move databases along with the associated instance level objects, such as logins, jobs, etc.SQL Server offers two upgrade paths in general: The upgrade path to SQL Server is different depending on the deployment pattern. A Subscriber to a merge publication can be all versions equal to or lower than the Publisher version which are supported as per the versions life cycle support cycle.For example: a SQL Server 2012 (11.x) Publisher can have SQL Server 2014 (12.x) and SQL Server 2016 (13.x) Subscribers and a SQL Server 2016 (13.x) Publisher can have SQL Server 2014 (12.x) and SQL Server 2012 (11.x) Subscribers. A Subscriber to a transactional publication can be any version within two versions of the Publisher version.Subscriber version depends on the type of publication:.A Publisher can be any version as long as it less than or equal to the Distributor version.A Distributor can be any version as long as it is greater than or equal to the Publisher version (in many cases the Distributor is the same instance as the Publisher).Ensure that you adhere to the rules regarding which versions are supported in a topology:

SQL Server supports upgrading replicated databases from previous versions of SQL Server it is not required to stop activity at other nodes while a node is being upgraded. Applies to: SQL Server (all supported versions) - Windows only
