You re-arrange and copy and paste it into Adwords Editor. Update campaigns, ads, keywords and bids in separate copy/paste updates.
This won't delete any new additions to the campaign, but it will "reset" the status, cpcs, etc. without having to do it line by line.
So you want "Make Multiple Changes" on each tab (Keywords, Ads, AdGroups, Campaigns...)
