You see an error "a data destinationorg is null" when trying to configure a new replication using VMware Cloud director Availability 4.7.2
There are some Organizations disabled in VMware Cloud Director
VMware Cloud director Availability 4.7.2
This issue occurs because some organizations are disabled in VMware Cloud Director and VCDA lists all the organizations when creating a replication with the system level user. This error will appear even if the destination Organization is not disabled.
Check if the destination Organization you're trying to configure the replication for is disabled
