They need to be migrated if you are going to use the new Chandler. That 
being said, they're "safe" there, we're not planning to decommission 
cosmo-demo yet.

That was briefly discussed on IRC and voted down: we're in the last days 
of alpha4 and we want to reduce code churn as much as possible. Adding 
this (arguably a new feature) at the last minute doesn't feel safe quite 
frankly. Especially if people rely on it for their data integrity.

Do you have a lot of non-event data? I personally had few tasks and 
emails so I prefixed the title of those with "Email:" and "Task" so that 
I could sort them rapidly and restore their integrity when importing 
them back. Not a workable solution though if you've a lot of them I have 
to admit.

As I said, we're not planning to take cosmo-demo off line but we won't 
upgrade it to Cosmo 0.5 (which would require to wipe out the old data 
anyway). osaf.us is already using Cosmo 0.5.
