We currently use WP to run our intranet, but with WAMP. We are removing the server where WP is installed and plan on using Microsoft's Web Platform Installer. I am use to using phpMyAdmin, but with the Web Installer, it installs MySQL automatically (5.1 when 5.6 is already out there).
Question is for those that install WP on a server... do you prefer MS SQL or MySQL? and how easy are those two to manage (importing my phpMyAdmin database and such)?
