TUAW reports an Apple Sales document released today details the upgrade process for business and education customers willing to purchase OS X Lion when it comes out in July. Apple has already outlined the Lion Up-to-Date program, which will allow customers who have purchased a Mac from Apple or authorized reseller to get the new OS for free, by filing a request within 30 days of Lion’s release. According to the Sales document, the upgrade path for business customers will be the following: by calling 1-800-854-3680 or using the Business Store, a minimum purchase of 20 license will cost customers $29.99 per license. With the same minimum purchase of 20 licenses, Apple is offering “maintenance contracts” (which will ensure a free upgrade to the next version of OS X) at $49.99 per license.

As for education, schools will get Lion at $39.99 per license with a minimum order of 25 licenses as part of the Apple Software Collection package, which includes OS X, iLife and iWork. TUAW also explains other licensing and deployment options:

Existing Volume License, Maintenance, and Apple Education Licensing Program customers will receive one redemption code for each contract that can be used to download Lion from the Mac App Store. That single copy of the Install Mac OS X Lion application is used to install Lion on other Mac systems at the school or business.

Once the install app has been downloaded, administrators just copy it to the target systems and run the installer. Administrators can use the System Image Utility in OS X Lion Server to build NetInstall (link to PDF) or NetRestore images to assist in performing mass deployments.

Apple has announced OS X Lion will come out in July at $29 exclusively on the Mac App Store as digital download. More details on the upgrade process and re-installation options due to the lack of physical media will likely be posted soon after the launch of the OS.
