can a 401(k) r PS account be rolled over to a regular DB or a 412(e)(3) and the funds remain segregated?

Assuming the DB allows it, Can a 401(k) or PS account be rolled over to a regular DB or a 412(e)(3) and the funds remain segregated? I'm particularly concerned with the rollover to a 412(e)(3).

Don't see why not.

neither do I as long as plan documents (both) allow that

Thanks all. I've gotten the answer I need from you.
