The conflict resolver governs how the Queue Reader Agent handles different versions of the same row encountered during synchronization.
You can change the conflict resolution policy after the publication is created as long as there are no subscriptions to the publication.
NOTE: but this is only in merge replication only I tried setting a Publisher on a different SQL Server say Server A, and Subscriber on SQL Server B.
Configured a Transactional replication to replicate a single table.
Upgrade Advisor detected that you might have one or more queued updating subscriptions that use Microsoft Message Queuing (also known as MSMQ).
Replication no longer supports Message Queuing; therefore, the subscriptions will be modified to use a SQL Server queue. Existing publications that use Message Queuing are modified during upgrade to use a SQL Server queue.
If using queued failover option, run Queue Reader Agent for subscription initialization. Msg 20512, Level 16, State 1, Procedure sp_MSreplraiserror, Line 8Updateable Subscriptions: Rolling back transaction. is that poosible to have 10 publisher and one subcriber.i guess u have 1 publisher and 10 subscriber.
Replication detects any conflicts when changes are synchronized with the Publisher and resolves those conflicts using the resolution policy you selected when creating the publication.
The following conflicts can occur: When creating a publication and enabling queued updating, replication adds a uniqueidentifier column (msrepl_tran_version) with the default of newid() to the underlying table.
When published data is changed at either the Publisher or the Subscriber, the row receives a new globally unique identifier (GUID) to indicate that a new row version exists.
SQL Server Replication provides multi-faceted data movement capabilities across SQL Server releases which has been used by customers across the globe for a large number of years.
When moving from one major release of SQL Server to another, replication topology upgrade has been a constant topic of lengthy discussions.
