New iMac 2012 continued multiple questions

[bedouin]

Have an apple account - not a problem.

I think I would like to copy all my old messages (texts and SMS) from my other iMac (two) and install it on my iMac (three).

I am surprised there is not any info on this via google.

My be pretty easy - one of the files in the library in messages?

Has anyone does this before?
