Omnidbutil -readdb import error on test server 7.03

Hi. I try today upgrade procedure from 7.03 to 8.1. Stuck at point 6, import IMDB on test server.

Command issued from cmd.exe window, Run As Administrator.

 

C:\Temp>omnidbutil -readdb -cdb c:\temp\cdb -mmdb c:\temp\mmdb

Database import will overwrite old database. All data will be lost!

Are you sure (y/n)?y

* Add 1 extension files for tablespace fnames.dat.

 

Command completes about 5 seconds, no IMDB import happened.

 

Export from production server wotj 7.03 Cell Manager is OK.

 

Please help.
