Hi Sebastian,
Please note that the integratorID is the first parameter that is taking into consideration when the communication is made with your Direct Entitlement set up.
So, as long as the intergratorID has your old server path, these values will always be present.
The Service URL and Service AuthURL are only verified if the verification of the integratorID fails, so as a backup these the two values are being checked.
You will need to get in touch with your support team if you would like to update the URL of the integratorID.
Thanks,
Andrei
