The Release Preview Account
All customers with a NetSuite production account can request access to a Release Preview account when it is available. Release Preview is available twice a year, right before each NetSuite release. This account lets you test your daily business processes with the new features available in the upcoming release.
Initially, only users with an Administrator role have access to the Release Preview account.
Administrators log in to NetSuite at system.netsuite.com and switch to the Release Preview Administrator role. An Administrator can grant access to Release Preview to other users as needed for testing.
Users can also access their Release Preview account from the New Release portlet.
See the Release Preview Guide and the Release Preview Guide for more information.
