I looked for a post dealing with the licensing issue (https://www.atlassian.com/de/licensing/jira-software) , but couldn't find one. We have a lot of customers (in Germany), with less then 500 users, who users JIRA Software, Confluence, Bitbucket etc. For most of them, it is not possible, to move into Atlassian Cloud for many reasons.
We fear that our medium-sized customers will no longer be interested in purchasing Atlassian products in three years, and they will definitely not change to the Data Center Edition.
It would be interessting to hear some other thoughts about this issue.
