Opening an older db

[jda]

Ruslan, what's the best way to figure out if a db being opened in 
V2.x was made with V1.x?

Should we always try to open the db as a generic VDatabase and test 
for the SchemaVersion (assuming we used it, as I have been)? The 
close it an reopen myDB.Open(f) it is 2.0?

Or is there a way that doesn't involve opening each db, closing, and 
reopening  it (which will become wasteful, because once users have 
migrated all their databases to V2.0 this won't be necessary)?

It seems that this would be a good place for an exception/try-catch 
block. But when I trap the exception that's thrown the error message 
is blank...
