Supported upgrade paths

You can upgrade to Veritas InfoScale 7.4.2 only if your currently installed product has one of the base versions: 6.2.1, 7.2, 7.3.1, 7.4.1. If your existing installation does not have one of these base versions, you must first upgrade your current installation to one of these versions. Then, follow the procedures mentioned in the Configuration and Upgrade Guide for the component configured with your InfoScale product.

If you are on an unsupported operating system version, ensure that you first upgrade to a supported version of the operating system. Also, upgrades between major operating system versions are not supported, for example, from RHEL 6 to RHEL 7. If you plan to upgrade from one major operating system version to another, you need to reinstall the product. For supported operating system versions, see the Veritas InfoScale Release Notes.

Table: Supported upgrade paths on RHEL, Oracle Linux, and SLES lists the supported upgrade paths for upgrades on RHEL, Oracle Linux, and SELS.
