How to keep old IMessage chats while changing Apple ID
I am currently logged out of IMessage on my MacBook, which I used with my old Apple ID. When opening the application I am asked to log in with an Apple ID. In the background of that pop-up-window I can still see that my old chat histories exist. Since those are really important for me, I would like to keep them. If I log in with my new Apple ID solely on the Messages App – while Messages is disabled for ICloud on this Mac – will my old chats still be available next to my new ones? How can I achieve to keep my old locally stored Apple IDs chats?
