If you want to merge two Facebook pages, a certain set of conditions need to be met:

1. You need to be an admin of both pages.
2. The pages have similar names and represent the same thing.
3. Your pages have the same address if they’re in the same location.

If these points are satisfied and you want to go through with the merge, then go to the Page Manager site, request which 2 pages you want to merge, and continue on to confirm. If the pages can be merged then the likes and check-ins will still be the same posts, photos and such will only remain on one page.

So make sure you think wisely about which page you want to keep and which to merge into the other!
