We need a draw.io license for Confluence Server for 40 users. Is it correct that the cost in the 2nd year is 50% of the initial license payment?
With a one-time purchase of a license you will receive a perpetual license for the software, as well as license support from Atlassian for one year, which allows you to send support requests and update the software. After this initial support period has ended, you have the option of extending the support.
