Hapag and CSAV seem to be very reasonable not to destroy existing relations:
New Customer Contacts / voyage cut-over programme
February 19, 2015
Please be informed that your current points of entry within Hapag-Lloyd AG and CSAV will remain unchanged within Germany for the time being. We hope your transition is seamless.
In case of bookings have been placed already and effected by the attached voyage cut-over programme, we will contact you shortly how the transfer will take place. For sailings prior to the voyage cut-over, Hapag-Lloyd AG and CSAV have to operate as
two different carriers. For further details, please refer to our attached Customer News.
For further information please contact your local Hapag-Lloyd office.
