Can these new-school statements (or ones like it)

ALTER MIRROR SERVER xxx12A AS PARTNER log_file = 'C:\xxx\xxx12A.mlog';

ALTER MIRROR SERVER xxx12B AS PARTNER log_file = 'C:\xxx\xxx12B.mlog';

be used to add HA debugging to dbsrv12 engines that were set up with these options?

(or is there some way to add *.mlog files to a 24x7 old-school setup?)

-n xxx12A 
-o "C:\xxx\xxx12ALog.txt" 
-su nfr
-x tcpip(port=55500;dobroadcast=no)
