The ts guide is the offical documentation.
The dr server needs to be identical, nb installed to same path, same drive letter (if windows), nb installed at exactly same version.
The ip address can be different but the hostname must remain the same. Then using dr file from old server, recover the catalog, it is that straightforward.
You have carried out the task successfully, ok, you had to restart the services, but after a recovery I don't think that is unreasonable, providing the system then works, which you confirmed it did.
I think the ts guide covers all I have mentioned, there is not much else I can add, apart from deactivate any media servers if they do not exist on the dr side
Dr tests do go wrong, but the examples that I have dealt with have usually been when the catalog and other bits have been copied across and someone has tried a shortcut etc. or hostnames have been changed or nbu installed at different path etc.
A recovery to an identical server from tape is the most simple recovery , as opposed for example from recovering a catalog from copy two of an ost device which is a bit harder, and really is a case of making sure everything is identical,, then recovering the catalog.
