Hi,
thanks for the support, even if my version of ENTM is not most updated one.
Besides of the information I received from you I needed to come up with a combined solution. So for anyone who might encounter the same issue, here is what I did.
As my DMS was still working, this was my base to start with. (Btw. many steps are related to a case I had with Mr. Mueller)
1.) Backup Old DMS
2.) dmsmgr -remove -dh DH__
3.) The suggested data extraction with "dbmgr -e -l -f dms__.txt" and "dbmgr -f -m -r dms.migrate" didn't work for me because when trying the import those information I received an error. Other possibilities like sepmd -n, or via selang and subs DMS__ newsubs(DH__@<server>) showed a different error (Packing comand into buffer).
4.) secons -s
5.) dmsmgr -create -dh DH__
6.) remove files from folder DH__
7.) copy files from DMS__ into DH__
8.) remove subscribers.*, pmd.*, Pmd_log, Error_log and update.dat
9.) enter DH__ directory and issue "selang -d ." within selang "so is_dms-" and "so is_dh+"
10.) add the Registry settings as described above
11.) start ControlMinder
12.) sepmd -s DMS__ DH__@<server>
13.) if sepmd -L DH__WRITER doesn't show DMS as target -> sepmd -n DH__WRITER DMS__@<server>
