Migrating Dev site to a Windows IIS server

[Note: Previous experience with Drupal 7 but none with Backdrop.]
I am just beginning to develop a client's site in Backdrop. I set up a Dev site on the Linux-based host service I use for a person site. Eventually this will need to be migrated to the client's host service, which unfortunately is Windows IIS. What kinds of things might I encounter in doing that, and what steps will be involved to get it working there? If you can point me to some documentation that would be helpful. 
--Thanks--
