Looking or guidance to Migrate from SharePoint 2010 to SharePoint 2016

Another great tool for custom analysis - https://rencore.com/products/spcaf. Just from my experience, not all of your WSPs or solutions will be compatible with SP 2016, so do a real good review of customization and monitoring jobs.

If you are an excel guy, get an upgrade worksheet https://www.microsoft.com/en-au/download/details.aspx?id=30370 and add/modify contents as per your need.

An architecture level feedback, if possible please redesign your new architecture from scratch (not saying there would be a problem with current one) but SP 2016 has much more advantages with respect to feature upgrades and services management which could be taken advantage of.
