Hmm, 70k users. I'm not sure how it will work with that many. I haven't done it with that many. I also haven't done it on a live forum. It will probably work, but you might want to close it first to avoid users seeing themselves in the wrong group, and to make it go faster.

Anyway, you would do this:

1) In the admincp, go to Users > Prune / Move Users
2) For the usergroup, select the group you are moving users *from*
3) Enter 0 for "Has not logged on for x days"
4) Press 'Find'
5) Look at the list to make sure it looks like the users you want to move, then scroll to the bottom and select the "Move" radio buttton, and the group you want to move them to, and press "Go'.
6) You can repeat steps 1 to 4 to make sure no users are found in the old group.

and repeat the above if you have another group to move.

But as I said I've never tried moving 70k users this way, so I don't know if that will be a problem. If there's a limit on the users is shows in the list, you may have to do the above multiple times.

Anyway, once that's done, you would then go to the Scheduled Task manager, find the "User Promotions" task, and press the "Run Now" button on the right. That should promote all eligible users to the correct group.
