For clarity, I'd like to get a better understanding of what happens if we don't migrate from Jira Server. Just playing devil's advocate. On 16th February, I can still log in and use Jira, right? I could continue using Jira Server until such point that I encountered an error which I can't workaround and which I'd require Atlassian's help with. This could be weeks or months. Is this correct, or have I missed something?
