Migration To New Mac OSX hard drive


I am new here (1st post)

I have Photolab 3 elite (new to me) on my Sierra OSX hard drive, all was working well. I love this and my Nik plugs.
I have a brand new fresh install of Mojave 10.14.6 and would like to know how do I get my projects or data across from the old Sierra hard drive?

I cant seem to find any info on this



You can use the Migration Assistant to do that
