Upgrading from 7w to 44w

I’m sure I’m going to need some technical help. I installed my 7w laser a couple of years ago and it has worked like a charm. I’ve completely forgotten where I found information on installing it and setting it up. And of course, I’ve slept since then and I have very little recollection of what it took. Is there a good resource anywhere that will walk me through the installation and setup? I need to remove my 7w and install it on another Onefinity machine, and then I need to install this new 44w on mine.
