Overview of Installation
Before you install Tibco Data Virtualization, review the new features and bug fixes as documented in the TDV and Business Directory Release Notes. You can view it at https://docs.tibco.com/products/tibco-data-virtualization
Choose one of the options below:
1. For a new TDV installation, refer to the chapter Installing TDV, Studio, and Drivers.
Note: After TDV 8.x is installed, you can proceed with installation of hotfix or service packs. Refer to the sections About Hotfix Maintenance and About Service Pack Maintenance for more information on how to do this.
2. If you are upgrading within the same major version (for example, 8.x to 8.(x+1)), refer to the section About Service Pack Maintenance.
3. If you are upgrading from an earlier TDV major version (for example, 7.x to 8.x), and also want to migrate the metadata created in the earlier TDV version, refer to Upgrading from an Earlier Release and Migrating The Metadata.
Note: If you do not need to migrate the metadata, follow the steps as outlined in the chapter Installing TDV, Studio, and Drivers to install a new version of TDV.
4. If you need to apply a hotfix, follow the steps as outlined in the section About Hotfix Maintenance.
