Four nw4.x servers in a wan are to be upgraded to nw6. The primary & two others will be on new hardware, the fourth will be an inplace. An image of the primary server & a mock nw6 server was prepared for migration testing outside the production network. The migration fails with the final step, the target server is unable to transform nds. The NDS was not modified to eliminate the other servers prior to migration. Is this the reason for the fail, is something else remiss?
