To Delete Secondary NIs (NS/XL Rel.  2.2 or later) 

If you are migrating from NS X.25 3000/V (release V delta 7 or later) to 
NS3000/iX release 2.2 or later, make a backup copy of your NS3000/V
NSCONF file.  To migrate to NS3000/iX release 2.2 or later, you must
delete the secondary NIs in the NS3000/V NSCONF file before you use
NMMGRVER to convert it.
