The replication protocol in 2.4 is not compatible wit 2.3.

There is no easy way.  I'm rsync'ing one account at a time between 2.3 and 2.4 
with IMAP/POP and LMTP access disabled, followed by a reconstruct, and then 
enabling IMAP/POP and LMTP access.

Many terrabytes to go.

You could also look at imapsync but its slow.

Change altnamespace/no to false or Options -> Folder Preferences and choose the 
Trash, Drafts, and Sent folders again.

Changing the IMAP name space mid-stream confuses some/many IMAP clients.  Mail 
on Apple thinghies will not recover without deleting the account on the device 
and creating it again.

Don't ask how I know this. :(

Fastmail needs to protect against malicious users but barring an account being
compromised, the business world does not have that problem.  A config option 
would be
nice or very isolated code that can be easily patched out.
