We're moving away from a hosted e-commerce platform and need to migrate 50000+ customers, ideally keeping their passwords intact.
I requested the customer data(including encrypted passwords and salts) from our current host and they refused saying that it is against PCI compliance.
How would you provide this data to a second party while keeping to PCI best practices?
I've tried searching but I can't find the relevent information or PCI documentation for this use-case.
