Background Color Macro Migration Guide
Learn how to seamlessly migrate the Mosaic Background Color macro from Confluence Data Center to Cloud with our step-by-step guide. Ensure a smooth transition with clear instructions and best practices.
This step-by-step guide will walk you through the process of migrating Mosaic Background Color macros from Confluence Data Center (DC) to Confluence Cloud.
Pre-Migration - Prepare for Migration
1. Audit of Macro Usage
Before beginning your migration, identify all pages using Mosaic macros, particularly any using nested macros. Our Mosaic Usage Report tool can help you do this by listing all pages containing Mosaic macros and showing their migration readiness status.
To use the Mosaic macro reporting tool:
- Click the Cog>General Configuration in the top-right corner to open Confluence Administration.
- Navigate to Mosaic Macros.
- Click Mosaic Usage Report.
- Click Start scan. The scan will begin.
- Once the scan is complete, click to Download Report.
2. Review Nesting
Confluence Cloud imposes stricter nesting (where one macro sits inside another) limits than Confluence DC. Make a note of any pages containing nested Mosaic Background Color, as these may need adjustments post-migration.
Pages with extensive nesting, especially when combining third-party and Mosaic macros, may not migrate correctly. If this applies to your content, contact us for tailored support.
3. Assess CSS Style Sheets
If your macros rely on the CSS Style Sheet Macro, be aware that this styling may not fully transfer to the Cloud Editor.
- Review pages for any custom CSS.
- Document where these are used, as manual changes may be required pre- or post-migration.
Migration - Migrating Pages with Footnotes
1. Run the Atlassian Confluence Cloud Migration Tool
Refer to Atlassian’s documentation for guidance on using the migration tool.
When using the Site Import method:
- Pages are imported into the new Cloud site using the Legacy Editor.
From January 2026
- Pages are imported into the new Cloud site using the Cloud Editor.
2. Review Migrated Pages
Once the migration is complete, open the migrated pages that contain Mosaic Background Color macros.
Your Background Color macros should appear as expected in the Legacy Editor in Cloud, however, styling applied using the CSS Style Sheet Macro may not be reflected. Basic editing is available for the Background Color macro, and colours can be changed. Please note that colour shades may vary from DC to Cloud.
If your Background Color macros are heavily nested, they may not appear as expected.
Post-Migration - Upgrade to the Background Cloud Macro
1. Convert to the Cloud Editor
Before transforming your legacy Footnote and Footnotes Display macros into Cloud Footnote and Footnote Summary macros, you must convert the page from the Legacy editor to the Cloud editor.
- Open the page you wish to convert and click Edit.
If your page is using the Legacy editor, a notification bar will appear at the bottom of the edit screen. The first time you view a page in the Legacy editor, you can switch to the Cloud editor by clicking Update Page in the notification. - When prompted, click Preview page → Convert Page.
Alternatively, you can choose to preview the page before converting. - The page is converted to the Cloud editor. All Background Color macros are now placed within legacy macros.
2. Rebuild Background Color macros using Cloud Background Macro
Rebuild your Background Color macros using the Cloud version of the Background macro to take advantage of the modern Cloud Editor and CSS-free styling.
- Refer to our Background macro documentation for step-by-step instructions on rebuilding your macros.
- Enjoy features like simplified editing and consistent styling.
