Is there any way to keep the rules when moving the pst between

If Exchange is not part of your mail profile, your rules will be in your PST
and they should be there if you configure your PST properly on the
destination PC. You may need to open each and reset the condition to get
them to work again, but they should be visible, at any rate.
