Upgrade path from 3.6 to 4.0

Greetings.

We have a store running nopCommerce 3.6.  Is there a compelling reason to upgrade to 4.0 one step at a time: 3.6 to 3.7 to 3.8 to 3.9 to 4.0?  Or should we be able to go directly from 3.6 to 4.0?  We have a lot of custom code and I'm thinking that every step along the way will require me to rewrite the customized stuff.

Any advice is appreciated.

Upgrading the database requires one step at a time.  Run each upgrade SQL script.

yes, you have to run script like 3.6 to 3.70 , 3.70 to 3.80 , 3.80 to 3.90 so on.

just paste your custom code from 3.60 to any version you have to upgrade.

Boom..!!

your store is ready with upgraded version.

Hope you will understand..!!

This part is what stresses me out.  We made a ton of changes to the source and wrote plugins for our CRM system and a bunch of other systems we have here, so I'm worried that lots of that will explode and need to be re-written -- especially in 4.0 because of the change to .Net Core.

In my opinion, it's impossible to move your solution without modifications. It's not true that you will have a working project after pasting your existing code. You need to be ready for fix problems. Amount of incoming work depends on number of your changes.
