Entity Versioning Issues

Hi,

I have another question about the entity version.  When the entity is evolved, the version of the entity should be increased so that the engine will try to convert its data.  Under some circumstances, if we want to switch the program to a previous version, an incompatible exception will raise.  What should I do to convert the data back to previous version?

Another scenario.  If two programs are visiting the same database and one of the program get evolved while the other program is running( the database is opened), what will happen for both of the programs?
