How to migrate OpenBSD?

Question

OpenBSD

Welcome all.
There was a necessity to transfer system (OpenBSD) on other screw.
There is a recipe for FreeBSD, there is a porting method for linux.
In general, it doesn't matter how to transfer the content, the main thing is to "fasten" the loader.
I just have no idea how to do it. Google is a bad helper.
If anyone has experience, please share.

Answer 3

you write install63.iso to a disk or install63.fs to a flash drive, boot from it and go to the shell. At the same time, you have an old disk sd0, and a new disk sd1. In this shell you say:
dd if=/dev/sd0 of=/dev/sd1
Wait for the end of the process. This is where the instruction ends. And so you can any system, even if you transfer Windows to another disk.
