At 59.5+ you can take out your personal contributions and do whatever you want, but to another 401k would be subject to their (other 401k sponsor) rules. Not sure why someone would do that from the DL 401k but I guess you could. Now to an iRA/SDIRA, I could see it. Company contributions and any in plan Roth conversions cannot be moved until separation (retirement). All of this info is within the SPD that in accessible on both DLnet and Netbenefits.
