In addition to the changes made in earlier versions that required migration, note also the following changes that may require action. These changes occurred after the release of version 3.0.1. Some changes were issued in hotfixes.You can import 3.x projects using the BusinessEvents Studio user interface. You can also import a 3.x project at the command line.These procedures are provided in TIBCO BusinessEvents Developer’s Guide, because they may be needed outside of a migration context. See the section Importing Projects from Earlier Versions for details.In 3.x and earlier, runtime properties were set using individual properties set in one or more TRA files. In some cases, runtime properties were set in TIBCO Designer, specifically in the BAR resource.In 4.x, runtime configuration is largely accomplished using a structured XML file called the Cluster Definition Descriptor. An editor in BusinessEvents Studio enables easy maintenance of this file. This file provides organization and structure so that related properties are shown in a logical relationship to each other.Most of the 3.x runtime properties are included as elements or attributes in the CDD file.Some properties are not relevant in the 4.x product, and additional properties not used in 3.x have been added.The migration utility creates a CDD file using all known properties that can be automatically migrated.You must also check to ensure all properties are migrated. You may have to add some properties manually.A new backing store implementation is included. Instructions for migrating form the Oracle-only backing store to the JDBC backing store are provided in TIBCO BusinessEvents AdministrationAny 3.x project libraries included in your project are not compatible with 4.x and the migration utility does not migrate them.If you want to continue to use the 3.x project libraries, add them to the 4.x project after migration. Follow instructions in the section Creating and Using Project Libraries, in Chapter 2, Project Tasks of TIBCO BusinessEvents Developer’s Guide.As BusinessEvents develops, the number of reserved words increases. Check the section Keywords and Other Reserved Words in Chapter 16, Rule Language Grammar, of TIBCO BusinessEvents Developer’s Guide. If you use any of the listed words as identifiers, resource names, or folder names, change them before migrating the project.Certain properties that were used only in the context of RMS are used more widely now. Their names have changed accordingly.
