Yes. Those instructions are slightly misleading as they refer to 
upgrading from 0.45 to a version which was not backward compatible with 
it.

For regular upgrade (i.e. between backward compatible release, e.g. 
most of them), you simply need to copy the new binaries over your old 
installation. That's all.

Specifically, all your data are located under '<ZOE>/Library/SZ/'. This 
is where all your messages, indices and preferences are stored. And 
this is the only directory you need to conserve during updates.

You can do this in two ways: copy the new binary distribution over your 
existing installation, or move your 'SZ' directory to the new binary 
location. Always have a backup handy though :)

Yes, this should be enough as long as you keep all the content of the 
'SZ' directory.

Hmmm... not quite sure what this does for you... do you want to run 
multiple instances concurrently?

Hmmm... ZOE itself doesn't provide a built-in IMAP server, only a POP3 
server.

Are you trying to migrate your data from one instance to another by 
using the built-in POP3 server? While this is a good way to move things 
around when necessary, this is slightly overkill in most situation. As 
far as upgrading goes, you can simply copy the new binary distribution 
over your existing installation.

Hmmm... by default the app always leaves all the messages on the 
server. If this is what you want, make sure that 'Leave messages on 
server' is enabled under your account preferences.

Cheers,

R.
