Error during creation of a directory server instance from an existing instance
If the version of DB2® on the source and target server are different, the idsideploy tool displays an error when you create a directory server instance from an existing directory server instance.
During the creation of a directory server instance from an existing directory server instance, the idsideploy tool takes online backup of the source database, including the logs. At the target server, the database is restored with rolling forward of logs to bring the database to a consistent state. However, there is a limitation when the target database DB2 version is later than the source database DB2 version. The rolling forward of logs from a previous version to a later version of DB2 is not supported.
Therefore, when you use the idsideploy tool, you must use the same DB2 versions on the source and target server.
