Frequently asked questions
What's a subscription ?
A Z5 OS subscription gives you technology, assurance, and expertise. It gives you access to enterprise-ready software, updates, and information and support services that span your entire application infrastructure, life cycle, and architecture, and you can receive the latest product versions. A Z5 OS subscription gives you access to multivendor support with thousands of software vendors, hardware vendors, and cloud and service providers that certify their technologies for our environments.
How long the subscription last ?
Subscriptions are typically 1 year 0r 1 month in length and are provided on a per-instance or per-installation subscription basis. Subscription start dates are governed by the original purchase date (if not specified otherwise in a contract). Subscriptions purchased online activate immediately. We’ll adjust subscription start dates in the case of a Z5 OS error, but won’t adjust them due to delayed hardware or software deployments on the customer’s end.
What's the renewal process ?
We’ll send renewal notices before your subscription ends, with links and information on how to renew your product subscription.
What is the difference between the standard and professional renewal upgrades ?
If you want to upgrade your subscription support level, you must place a new product order. For example, if you want to upgrade your subscription support level at the time of renewal, don’t renew your existing subscription. Instead, purchase a new subscription with the upgraded support level. If you choose to downgrade your subscription support level, just place a new product order.
