I just finished an across-the-wire migration from a NW 5.0 server to a NW65
server using the migration wizard.

Everything went fine until Step 4.

Step 4 states that it upgrades schema, fixes volume objects then restores

From all indications (reviewing error and success logs) all three of these
processes completed. I get a message on the migration wizard that it
failed and the last step to complete is the restoration of Trustees.

The error log has this entry:
"- ((You may be able to look in SYS\SYSTEM\MIGERROR.LOG file on the
destination and/or source server for more information about this error.)
DSInstallProducts Xfffffda0 - NDS error: An attempt was made to add a
property that is illegal to an object. The NDS schema determines what
properties can be inherited by an object class.) Can't install products on
the server CHADMIN-1. (LDAP)"

and the MIGERROR.LOG file contains this entry:
"0xfffffda0 NWIDS_InstallDSProducts null"

Any suggestions?

Everything appears fine except for odd things like missing "some"trustees;
not all and connectivity issues to the server from the clients.
