Newbie alert  -- please be gentle.

I have a home Calendar Server instance that's been happily running on Leopard since November 2007, serving three Leopard iCal clients.   For the most part it's been running fine but there have been some odd quirks in calendar event creation lately.  It strikes me that it would be prudent to refresh this with the latest build.

Here's what I plan to do:
  1. Shut down the existing instance
  2. Back up my master CalDav directory and all the current calendar data
  3. Execute this Subversion command to obtain the latest build
  4. Recompile and restart the instance
Is this a valid approach?  Do I need to worry about any XML metadata changes between the existing calendar data and the current build as of May 23?

Regards,
Steven
