Jira Server and Data Center do not understand Markdown at all — their descriptions and comments use Atlassian's own wiki markup, where bold is *text*, headings are h2., and code lives inside {code} macros. Paste raw Markdown there and you get literal asterisks, hashes, and backticks.
Jira Cloud's newer editor accepts some Markdown shortcuts while you type, but it handles pasted Markdown inconsistently: tables, fenced code blocks, and nested lists often break. Converting to wiki markup first makes the formatting reliable in both flavors of Jira — and in other Atlassian tools that share the same syntax.

Headings (h2.), bold and italic, monospace, {code} blocks with language, bq. and {quote} quotes, nested lists, [text|url] links, !image! syntax, and ||header|| tables.
