It's a lot more than zero seconds to rebuild a big file server; converting 8TB
of data from any fs to any other fs is a lot more than a few hours.  Alas, the
O/S distro that I'm currently using precludes the zero-effort solution that
you recommend: btrfs has only been supported in very-recent O/S distros.

Once I modernize these servers then I'll look into the btrfs conversion.  I
presume that btrfs is gaining traction faster than zfs but I'll leave that to
the experts here.
