If you are having problems during the file copy, try one or more of the following:
Enable login on both the destination and source servers. If you have disabled login before you started the file copy, the servers can't log in to each other in order to migrate the files.
NOTE:If you have selected to do so, Migration Wizard disables user logins for you during the migration.
If files are copying very slowly, make sure that the servers and workstation are configured at the highest common LAN speed. Verify that the NICs and anything in between are all hard coded to either communicate half-duplex or full-duplex; they need to be the same throughout. If there are problems with full-duplex, use half-duplex.
NOTE:If compressed files are migrated to uncompressed volumes, file copy might be slower.
If Migration Wizard encounters filenames with a total path length of more than 256 bytes, the file copy stops. You might need to reorganize the data on your source server if your path lengths are longer than 256 bytes.
