Deployment and upgrade process
As of version 5.0, IBM® Rational® Requirements Composer is renamed to IBM Rational DOORS® Next Generation. For more details, read this Jazz.net blog post.
The upgrade process is a side-by-side installation. Each product must be upgraded by installing the new version of the product and updating configuration files, adding or updating tables in existing database repositories, and upgrading the data warehouse. For an overview of the workflow, see the flow diagram at Example: Upgrade stand-alone products to an integrated solution.
Before you upgrade a production system, you should always test it first in a test environment. If this is a test upgrade, remember to set the older version's configuration files to point to the database clone and not the production database. For information about setting up a staged test environment, see Staging a test environment for the upgrade process.
Upgrade order
If you plan to upgrade multiple products, follow these guidelines to determine the optimal order for performing the upgrades. In part, the order depends on the reporting solution that you used in version 5.0.x and will use in version 6. For further information about the impact of reporting on the upgrade process, see Reporting and the upgrade process.
If you use Rational Insight for reporting, Rational Insight needs to be at version 1.1.1 or later before you upgrade the CLM applications.
In a CLM deployment, Jazz Team Server must be upgraded first.
Upgrade instructions
Step-by-step instructions are provided in the Interactive upgrade guide for performing an upgrade of each product using the upgrade scripts that are provided. Additional instructions are provided for performing a manual upgrade without using the upgrade scripts. It is recommended that you follow the upgrade script instructions if you are deploying to a single server or if you are performing a distributed deployment and you can mount and access the drives where each application and the Jazz Team Server (JTS) are installed. Follow the manual upgrading instructions if you are performing a distributed network deployment and you cannot access the network drive. If you are upgrading from version 4, follow the steps in Upgrading from version 4 to the current release, and then use the Interactive upgrade guide.
Deployment considerations and limitations
In a CLM deployment, Jazz Team Server must be at the same level as or newer than the applications that are registered with it, but the applications cannot have a newer version than Jazz Team Server. If you have a distributed environment with separate application servers or separate WebSphere Application Server profiles, you can upgrade each application separately. But remember, Jazz Team Server must be upgraded first. If you have one server, you can upgrade all products at the same time.
You can upgrade a single product or multiple products. If you plan to upgrade multiple products, it is highly recommended that you upgrade a single product and verify the success of the upgrade before moving on to the next product. Jazz Team Server must be upgraded first.
If you upgrade multiple products that were on multiple application servers, those applications will continue to run on separate application servers after the upgrade. You cannot merge multiple products into a single application server. However, you can still register multiple applications with the same Jazz Team Server application.
Database deployment considerations
Consider the following deployment plans for your databases.
- Be sure to back up your databases before beginning the upgrade.
- If you use DB2®, Oracle, or SQL Server, review the instructions in the database setup topics before starting the upgrade. Proper database tuning is essential for optimized performance during the upgrade. For details about database setup, see Setting up a DB2 database, Setting up an Oracle database, or Setting up an SQL Server database.
Impact of an upgrade on your deployment
The version 5.0.x and version 6 Public URIs for each application must match. See Planning your URIs for further details about Public URIs.
