Delta products are available with maintenance contracts that provide access to a range of support services and any necessary patches for reproducible problems.
Support for additional target platforms is not included within the scope of the maintenance contract and requires the purchase of additional licenses for the new targets. Most additional licenses can be supplied online with little or no impact on active customer projects.
All Delta products include sophisticated tools to support the correct installation of product patches. Tools are also supplied for any necessary migration of project specific information from one product release to another.
