1. Inventory the macros
Record the current diagram app, page count, owners, source-file location, and whether the diagram must remain editable or can be archived as an image.
Atlassian’s three-year Data Center wind-down is underway. Audit the app path, test the source files your pages actually depend on, and move supported Visio, Lucidchart, Gliffy, Mermaid, SQL, and saved diagram files into editable Confluence Cloud diagrams.
No bulk-migration or perfect-fidelity promise. Keep your originals and verify before cutover. See the primary sources.
Start with the app assessment
Atlassian’s Confluence Cloud Migration Assistant assesses Marketplace apps and shows whether an app has a Cloud version and migration path. Atlassian also lets you mark an app as not needed or choose an alternative. That decision is the start of diagram migration, not proof that every embedded diagram will arrive editable.
Record the current diagram app, page count, owners, source-file location, and whether the diagram must remain editable or can be archived as an image.
In the assistant, distinguish an automated path from Contact vendor, No, or an intentional Use alternative decision. Do not infer support from a Cloud listing alone.
Test complex and multi-page files before the migration freeze. Verify labels, connections, custom imagery, layers, and any warning—not just whether the file opens.
A file-first runbook
Use a representative sample to decide the route for each source family, then apply the approved route to the rest of that family.
Export the Cloud Migration Assistant assessment. For each legacy diagram macro, name an owner and capture the vendor’s migration status before choosing an alternative.
Keep the Data Center page export and original editable source. An image is useful evidence, but it is not an editable migration source.
Pick at least one simple, one complex, and one multi-page file per format. Include custom shapes or embedded images if those appear in production.
Use the free browser editor or ask us to test one sanitized file. Check the imported pages, objects, connectors, labels, and warnings.
Install diagram.now, add it to a Cloud page, and run the same supported import. Save, close, reopen, and make a small edit to prove the result is live—not a screenshot.
Compare the Cloud page with the source, retain an exception list, and get the content owner’s approval before the Data Center copy becomes read-only.
Current importer coverage
These are diagram.now’s current, deliberately narrow import contracts. Vendor-specific features outside them may be simplified or skipped.
| Source | Give diagram.now | Editable result | Migration note |
|---|---|---|---|
| Microsoft Visio | .vsdx | Pages, supported shapes, labels, connectors, and supported images | Legacy .vsd is not accepted. Convert to .vsdx first. Custom masters, nested sub-shapes, and specialized objects need visual review. |
| Lucidchart | .lucid archive | Pages, mapped shapes, text, links, and connectors | The archive must contain Lucid’s document data. Keep the source; unsupported types can be mapped to simpler editable shapes. |
| Gliffy | .gliffy export | Supported objects, text, shapes, and connections | Export the editable Gliffy format—not PNG, JPG, or SVG—when editability is the goal. Review any importer warnings. |
| Mermaid | Paste flowchart or graph source | Editable nodes, edges, directions, subgraphs, and supported edge labels | Only flowchart/graph syntax is promised. Sequence, class, state, ER, Gantt, and other Mermaid diagram families are outside the current importer contract. |
| SQL schema | Paste CREATE TABLE DDL | Editable ERD entities plus primary/foreign-key relationships | This is schema-to-ERD conversion. Stored procedures, queries, data, and vendor-specific database behavior are not migrated. |
| Saved diagram.now file | .diagramly, JSON, or diagram.now XML | Native pages, shapes, and connectors | PNG, SVG, and PDF reopen as editable only when diagram.now created them with embedded source. A flattened third-party export stays flattened. |
It does not promise direct draw.io/mxGraph conversion, automatic macro replacement, bulk migration, or pixel-perfect fidelity. Use the installed app’s documented path when one exists; use representative-file testing when you choose an alternative.
A real migration check
Tell us the source format and what must remain editable. We’ll test one representative file and reply with what imported, what needed cleanup, and whether the current route is suitable. No sales deck is required.
Current Atlassian Marketplace pricing
Pricing below is the diagram.now Cloud app price shown by Atlassian, not the price of your Confluence subscription. Fact-checked against Atlassian’s live Marketplace price table on July 19, 2026.
Atlassian bills the app against the host-product user tier and may display local currency, tax, or later pricing changes. Verify the live price before purchase.
Migration FAQ
No. Marketplace app migration is app-specific. Use the assistant’s app assessment to confirm whether an automated path exists. Depending on the result, Atlassian may direct you to upgrade, contact the vendor, mark the app not needed, or choose an alternative.
Not directly. The current importer accepts .vsdx. Convert the source in a compatible Visio version, keep the original .vsd, and compare the converted file before migration. Microsoft identifies .vsdx as the editable drawing format for Visio in Microsoft 365.
No. Imports prioritize an editable result, and complex vendor-specific features, custom shapes, nested objects, or unsupported elements can be simplified or skipped. Preserve the source, read warnings, and have a content owner approve representative examples.
Supported imports in the free editor are parsed in your browser. The optional one-file help path is different: emailing a sample sends it through email, so use only a non-sensitive or sanitized file and never send confidential material.
Not through the migration workflow documented on this page. Do not rename a draw.io file and assume compatibility. Keep the original and use the one-file help CTA if you want us to inspect a representative file and explain the current options.
Yes. Atlassian’s live price table currently lists the diagram.now Cloud app at $0 for the 1–10 user tier. This is app pricing; your Confluence plan is separate. The same table currently lists $142.50/year for 15 users and $475/year for 50 users.
