JDE 8.10 Expiration Date

Dear Expert,

Customer is using JDE OneWorld 8.10, customer concern on the expiration Date, the following is the questions:-

1. Does the Expiration date can be change/ be set by end user or not?

2. If the expiration date is auto fill based on the license date purchase (eg. 30/6/2019), does it mean the users cannot log in to JDE on 1/7/2019 if not apply the re-license?

Hope to hear from you soon.
