I saw on one of the trade threads someone said that they couldn't transfer more than 6 Pokemon in one day. While obviously this is true, there's a way to get around it. I'm new to the forums, if this has already been posted/everyone knows, you can delete this and I apologize. For anyone who doesn't know, (I did a search, didn't find it, so maybe this hasn't been posted. I don't know), here's how to do it. It requires messing with the internal clock, but it's worth it.
1. Send your Pokemon through Pal Park though one of your 3rd Gen games. Go do the normal Pal Park stuff.
2. Turn off the DS and turn it back on. Set the day on the DS one day ahead.
3. Turn it off and insert a different 3rd Gen game.
4. Attempt to send stuff from the new game to Diamond/Pearl. It'll be told you need to synchronize. Say yes. You can't migrate for 24 hours.
5. Reinsert the first 3rd Gen game. You're now free to migrate from that game again, it won't give you any problems
6. Repeat and recycle.
