Today I had a scenario to migrate just a site from SP2010 to SP2016. For this there are 2 ways, which I know, 1. Use any 3rd party tools like ShareGate, etc., 2. Use DB backup and restore into SP2013 and mount-database and test-spcontendatabase and now your SP2013 site is ready. Repeat the same for SP2013 to SP2016. All this steps are done in Dev environment and as last step, particular site will be exported from SP2016 dev environment and imported to SP2016 production environment. But I found some blog which shows 3 steps especially for lists, https://absolute-sharepoint.com/2013/08/how-to-move-a-list-from-sharepoint-2010-to-sharepoint-2013.html Go through the link and take advantage of it, if there is a need for list migration.
