Custom Platform Logos Lost After Upgrades

Custom platform logos that were previously uploaded and displayed correctly in the DataHub UI disappear after a version upgrade, reverting to default platform icons.

Note: For DataHub Cloud customers, infrastructure-level changes are managed by DataHub Support.

1. Re-upload custom platform logos:

   • Navigate to Settings → Appearance → Platform Logos
   • Upload logo files again for affected platforms
   • Ensure logo files meet size and format requirements (PNG, SVG recommended)

2. Check if logos are persisted:

   • Verify logos are stored in proper location (check with support for cloud)
   • Self-hosted: logos may be in volume mounts or database
   • Confirm logos survived upgrade by checking file system

3. Prevent logo loss in future upgrades:

   • For self-hosted: ensure logo volume mounts are persistent
   • Document custom logo files and locations
   • Back up customization settings before upgrades

4. For cloud customers:

   • Report missing logos to support immediately after upgrade
   • Provide logo files to support for restoration
   • Support can verify if logos need to be re-applied

Test configurations in a development environment before applying to production. Always backup configurations before making changes.
