Migrate data from one customer to another

Hi,

We have a setup of SMAX 23.4 and CMS 23.4 (containerized) with NativeSACM enabled and we need to migrate the CIs, relationships, rules, etc from one customer to another.
How do we do that?

I've read this: https://docs.microfocus.com/doc/SMAX/23.4/PushDataBetweenCmsCustomers but it seems that multi-tenant isn't supported.
