Has anyone used MS Web Deploy to move DNN from one webserver to another?

I recently did - have two DNN sites which are virtual directories under a website, along with about 20 other vdirs/apps.

One of the sites was missing nearly 100 files out of 13,700+, whereas the other had all 16,000+ files to the exact number.

Didn't see any issues with the non-DNN directories. Used Robocopy to pull over the missing files.

Thought that it might have to do with locks on some files - the site was still live - but that doesn't seem too persuasive given that they were text files, css, ascx ... and for the web. Multiple simultaneous reads expected.

Just curious whether anyone else has had experience here. On the whole, very happy with how Web Deploy was able to take an entire website from IIS 6 and move it to IIS 7.5, reading the old-style configs and implementing them in the new environment. Slick.
