Depending on how much slurry you have, you may not want to use all of it. Use one of the pitching rate calculators to determine how much slurry you need. If you underpitched your lager (like most people do) you may have just enough to do another batch.
It may not be ideal for you to re-use the slurry in a typical light lager since a Schwarz is often more flavourful. A dunkel or bock should be fine, or maybe a rauchbier. 2206 gets lots of respect in the brewing literature as a versatile and effective strain, although I personally have never had much to do with it.
