OK I think I'm at least a small step further.

I realized that tdbbackup failed on 
'DC=DOMAINDNSZONES,DC=COMPANY,DC=INTRA.ldb'

trying to restore a tdbdump failed due to a duplicate key error. I 
removed that dup key row and finally was able to tdbrestore and then 
tdbbackup all databases.

I created an domain offline backup via samba-tool and restored the 
domain to a new system.

Trying to join a dc the restored domain now fails with

dumping the secrets.tdp I can find

any hint is highly welcome
