Wrong trust and certificate after hostname change

Hi all

I do have issues with certificates and trust like I mentioned in another thread but here is a different one. I did need to change hostname of two systems because the customer deliver wrong information at the beginning. I did that by GUI within Hardware-Ethernet......

old name = EMCDD01.CUSTOMER.LOCAL

new name = DD040B01.CUSTOMER.LOKAL

After changing the hostnames and a reboot it tells me in the CLI the following

root@DD040B01# hostname

The Hostname is: DD040B01.CUSTOMER.LOKAL

root@DD040B01# adminaccess trust show

Subject Type         Valid From Valid Until Fingerprint

the same for the other system. What is the supported way to change hostname?

I am pretty much sure that this will lead to certificate issues anyway even more then I have. I have to be honest I am a little bit stressed about all this atm.
