How To Cross Promote Pages? Can You Contact All Your "LIkers"?

Basically I have 2 pages. One thats just starting out and one that I have had for a while but stopped promoting like 2-3 years ago. That one has like 2000+ likes. I want to be able to tell all the people on that page about my new page. Is there a way to message all my likers? Or is the only way to contact them is to make a post on the wall and just hope it reaches everyone?

Is this not possible?

You should post a link to the other site and boost it until most of your fans have seen it. I don't know any other method to reach much of your fans..

That option existed probably like around 7 years ago (contacting all facebook fans on a page) ever since your only option is post and hope they see the post, but as time goes bye less and less people see it so unless you pay facebook to promote the post, you will have very poor results

your best option is probably to, try merging the pages. even boosting it and announcing a move may not get favourable results
