We'd rather not get involved in that part of process if possible. You or your team should try to extract the data yourselves, or ask for support from your current platform provider if you are having difficulty. Unfortunately many platforms put up barriers to you getting your own data, so the process can be somewhat painful.
If you're really stuck, we will of course try to help.
See our [Data Export/Import FAQ](/faqs/data-export-import-faq) for more details.
