 I want to upgrade jira service desk v4.5.5 to jira service management v4.21.0 ，Since my environment cannot be directly connected to the Internet ，so which span versions do I need to upgrade to first ？Thanks a lot！

Hi,

Welcome to Atlassian Community!

Follow the official instructions. It should not be a problem to upgrade directly to version 4.21.0. Remember that it is recommended to upgrade to TEST environment first and verify that everything will be without problems.

Thank you for your reply.Last week, I followed the official instructions to perform repeatedly direct upgrade test in the test environment. But it's broken and the project won't open. Then I came to ask the question.So I think there should be an intermediate buffered version.

OK, I can try to take a closer look at your problem. I need to know exactly what the problem is and what the output of the Atlassian Jira log file is.

Alternatively, you can still write to https://support.atlassian.com/ for official help.
