Server migration Windows 2008 to 2019 - impact?

Our company is doing a server migration and upgrading equipment. We currently use kanboard in one of our office with equipment using windows 2008. Is there application support that we can hire or have a discussion with regarding what impact this will have on the existing Kanboard app?
I’ve searched on the site, but thought I’d check here. NOTE: I am not very technical, so this may be easy, but not sure.
