Estimate only — not an official quote

Is your Atlassian Data Center instance ready to move to Cloud?

Drop in your installed-apps export (or a plain list of app keys), tell us a little about your instance, and see which of your Marketplace apps have an automated Cloud migration path, which need manual work, and which have no Cloud equivalent at all — plus the Data Center end-of-life dates and the Cloud limits worth knowing before you commit — all worked out in this browser tab.

Nothing you load here is uploaded anywhere. Every file is read with FileReader inside this browser tab and never leaves your machine — there is no server behind this page, and the strict Content-Security-Policy in the page source (connect-src 'none') stops it from sending anything anywhere. The only two things that leave this browser tab: a bare usage count (when the page opens, when a file is read, and when you click through to us, it requests an empty image from this same site with a timestamp and nothing else — nothing from your files) and one small preference cookie, rt_theme, that remembers your light/dark choice across every releaseteam.com tool — it holds only "light" or "dark", never anything that identifies you.

1. Installed apps

Fetch the installed-apps list from Universal Plugin Manager (UPM) REST while logged in as a Jira, Confluence, JSM or Bitbucket Data Center administrator, then save the response as JSON and drop it below:

How to get this file

While logged in as an administrator, open <base-url>/rest/plugins/1.0/ in the same browser tab (for example https://jira.example.com/rest/plugins/1.0/).
Save the page as JSON (most browsers: right-click → Save As, or select-all/copy into a text file with a .json extension).
Drop that file below. It never leaves this tab.

Drop the UPM JSON here, click to browse, or paste below.

Also accepts a plain text/CSV list of app keys (one per line, or a key column). Max 20 MB. Parsed in this tab only.

Or paste JSON / a key list

Data Center end-of-life timeline

Computed from today's date in your browser. Source: atlassian.com/licensing/data-center-end-of-life (as of 2026-09-28). Applies to Jira Software, Jira Service Management, Confluence, Bamboo, Crowd Data Center and Data Center Marketplace apps. Bitbucket Data Center is not going end-of-life — Atlassian offers it under the Bitbucket Hybrid License instead. Jira Align is excluded (not a Data Center product on this timeline).

Cloud limits worth knowing checks against Atlassian's published guardrails

Source: support.atlassian.com — data limits and guardrails. Only the limits below are verified against that page; this tool does not invent others.
