You will probably do well to install the version you are currently using on the new server, then stop all SM services, copy all the data and configuration files to the new server over the just-installed version, restart the services, and check for proper operation (you will of course need to configure IIS and stop the SM web service).
You should then verify that all is working as well as it was on the old server.
Then, you can do the upgrade in-place to v100(v17). Most of your original settings should be preserved - you'll need to double check things and read any notes about it here on the forum.
This is exactly what I did when moving from v11 to v15. It went well.
If you attempt it a different way, you perhaps risk compounding problems related to the migration itself, and the troubleshooting will be more difficult.
I am repeating myself here from previous posts: I am staying with v15 for the time being. It's very stable, and is all I need for the time being.
Just my opinion. YMMV
