Expiry Countdown
RED displays the installed license expiry countdown in days on the login screen. 
Expiry Date
You can continue to use RED UI’s and RedCli up to midnight on the date of your RED license expiry. The day following your expiry date you will not be able to use any RED UI’s or RedCli until a new license with valid expiry is installed.
Scheduled jobs will continue to operate beyond the license expiry date but you will not be able to administer those jobs nor add new ones. Any jobs which call RedCli or RED command line operations will start to fail.
Expiry Grace Period
Only ‘Partner’ licenses receive an expiry grace period of 30 days in which the product will continue to operate for 30 days beyond the license expiry.
