Actian Zen Cloud Server 15 Sidegrade from Zen v15 Server

The Actian Zen Cloud Server 15 database engine is the same core database engine as Zen v15 Enterprise Server, but it uses a capacity-based licensing model and is required (per the End User License Agreement) for SaaS and middleware/web environments. Sites with small databases and many users may also want to consider this pricing model.

The upgrades on this page are for users of Zen v15 Enterprise Server who want to move "sideways" to Zen Cloud Server 15. Actian limits the allowable upgrade paths from v15 Enterprise Server to Zen Cloud Server 15 based on this upgrade chart:

	From Zen v15 Enterprise Server User Count	To Zen Cloud Server 15 Size
	6 or 10 Users	Small (20GB data)
	20, 35 or 50 Users	Medium (100GB data)
	100 or 250 Users	Large (200GB data)
	500 or Unlimited Users	SuperSize (Unlimited)

If you need a larger Zen Cloud Server 15 license, you should first upgrade to the size for which you get the discount, then get a Zen Cloud Server Size Upgrade to move to the required size. If you need an interim size (such as 30GB), then you may wish to consider the Data Size Increase instead.

Zen Cloud Server 15 is available for Windows 32-bit or 64-bit, Linux 64-bit, and Mac OSX 64-bit, and you can switch platforms and bit levels at any time.
