The aim of these guidelines is to explain the availability of licences and support services for PROIV (non-mainframe) products as they move through the product lifecycle phases. You may also be interested in PROIV's Supported Platforms Guidelines.

In general, PROIV normal support services are available on...

•	The current major version (e.g. 6.x).
•	The previous major version (e.g. 5.x) for up to twelve months from the release date of its successor.

Note that PROIV operates a 'forward fix' policy whereby for each major version, fixes are only applied to the latest release of that version.
