How to remake old posts with new composer but keep the old post hit counts and stats

Hi guys, this is important to correctly display the most popular posts in any modules and pages. As this is such a critical issue when migrating to the new composer, I'm sure you've got it covered.

I know I can make a new post with the new composer and just copy over the contents of the old post. But how do I carry over all the stats (like hit counter) from the old post?

If need be, I'm ready to follow your instructions to do it via database, but please a batch procedure, not one by one.

Thanks
