We are trying this again and we keep getting the trustees backed up to the destination server. Can monitor the progress and have seen the files going onto the new server.
When it gets to the copy files stage, it starts out fine and appears to be copying files and folders, on inspection of the Volume on the destination server can see the files moving over. But it will "pause" on a file and sit there for a long time, then eventually it appears to time out and the wizard ends the copy phaze. When I inspect the error log it shows all folders and files after the "paused" file to not be created on the destination server. Inspection of the target volume confirms this. The success log shows everything as being fine.
this happens over and over. Tried this repeatedly. The only difference is that on subsequent tries the error log shows all files and folders that have been copied over already giving the error message that the files already exist.
