Merging a bigger page into a smaller one

Does anyone has experience of merging a bigger page into a smaller one? So far I've only merged small pages into bigger ones. For example could you merge a 30 000 page into a 1000 like page? I'm afraid to try this, don't want to lose the likes. But all the likes should transfer to the smaller page right?

hey i hope you do succefuly to merge big to small page... but i see that you have merged amoll pages before.. can you tell me the step by step TUT.. because i want to merge some smoll pages but i have try some method but without succes.. thanks
