Yes. As of writing, and for a limited time, current Server and Data Centre customers who move to a 1,001+ user tier cloud subscription are eligible for a discount on subscriptions of 12 or 24 months. This scheme applies to Server/DC customers moving to Standard, Premium, and Enterprise cloud subscriptions for Jira Software, Jira Service Management, Jira Work Management, and Confluence.
There will be sliding discounts depending on when you choose to move. The best discount will be available for Cloud purchases dated before July 1, 2021 PT. After June 30, 2023 PT, there will be no discounts available.
You must have purchased your server or Data Center license/subscription before February 2, 2021 PT, and it must be under active maintenance or within 30 days of expiry (so you can’t dig out an old Server license with no maintenance and use it to get a discount!) and your server or Data Center license must be migrated using a free cloud migration trial.
