Adobe Commerce (all deployment methods) 2.3.x, 2.4.x.
Create a “scrubbed” dump from the Admin:
/var/supportdirectory to the Adobe Commerce root directory.
You can then provide to Support the direct download link to the dump files (your store address and the file name as displayed).
If you have issues creating dumps from the Admin, consider using CLI commands as described in Run the support utilities in our developer documentation.
