There are several limitations for replication of Microsoft SQL Server large value data types.
You cannot define as a primary key a large value data type column in the replication definition.
You cannot define as searchable a large value data type column in the replication definition.
You cannot replicate stored procedures that include one of the new large value data types as a parameter.
You cannot use text pointers to manipulate the data of the new large value data types.
In a mixed-version environment, the primary and replicate Replication Server must have a site version of 15.2 and later and an LTL version of 710 and later.
See the Replication Server Heterogeneous Replication Guide for datatype issues with non-ASE data servers.
