Is it possible to import a wordpress backup from a single site in to a multi-site configuration?

I imported/exported between a single wordpress blog and a multisite wordpress without problems, many times.

Personally on a multi-site wordpress I have a parent generic theme and each website has it’s own child theme with as few files as possible, mostly only html/css for custom post types. Security issues or big complicated options are most of the time in the parent theme anyway, which means I keep improving all my websites at the same time.

It’s how I like doing, doesn’t mean I would advice to do the same because a working website has something wonderful: it’s working…

Anyway if you make a mistake with an update (plugins, themes or other) all the websites using the same help noticing earlier.
