Mixed-Version IssuesLocate this document in the navigation structure

In a mixed-version environment, the route version between the primary and replicate Replication Servers determines which features are supported.

  • Only Adaptive Server versions 15.5 and later support <bigdatetime> and <bigtime>. If the primary data server is at least Adaptive Server 15.5, and:

    • Primary and replicate Replication Server are version 15.5 or later, and the replicate Adaptive Server does not support the datatypes, you can create a replication definition containing a mapping for each of the two datatypes to the <varchar> datatype. Alternatively, use the <varchar> datatype instead of the two datatypes in the replication definition.

    • Primary Replication Server is version 15.5 or later, and the replicate Replication Server and Adaptive Server do not support the datatypes, use the <varchar> datatype instead of the two datatypes in the replication definition.

    • Primary and replicate Replication Server, and the replicate Adaptive Server do not support the datatypes, RepAgent automatically sends the <varchar> datatype to Replication Server.

  • For replication of a quoted identifier to succeed, the primary Replication Server and the Replication Server that connects to the replicate data server version must be 15.2. However, intermediate Replication Servers in a route can be earlier versions.

  • A replication definition created with <unitext> columns is not propagated to Replication Server version 12.6 and earlier.

  • A replication definition subscribed by Replication Server version 12.6 and earlier cannot be altered to add <unitext> columns.

  • A replication definition created with <unitext> columns is propagated to Replication Server version 12.6 or earlier if the <unitext> columns are removed.
