Third query, on 'reconstruct'.
I scp'ed test data from a dummy user to the new server, then tried
to reconstruct it, but reconstruct is not behaving as I'd expect.
To get reconstruct to work it appears I have to do two steps:
First (as per the upgrade page):
reconstruct -V max
But that doesn't add all of the emails... then running:
|reconstruct -f|
...does, like this:
[root@emp87 server]# reconstruct -V max

Otherwise the emails in subfolders are not visible over IMAP.
What is the correct process for running reconstruct from 2.4 to 3.0?
Also, once visible it appears messages are all "Unread" flagged -
can the seen flags not be brought through? These are emails from an
existing 2.4 server.

Hi Simon,
looks like you did not import a dump of mailboxes database on
destination. And also did not copy user,quota,sieve folders.
From my memory:
a) On $origin server:
- dump mailboxes.db to text file
# ctl_mboxlist -d > /tmp/foo
b) on $destination server:
- copy from _$origin with permissions(assuming default paths on rhel7/8):
/var/spool/imap/*
/var/lib/imap/sieve/*
/var/lib/imap/user/*
/var/lib/imap/quota/*
your /tmp/foo mailboxes dump file
- import mailboxes
# ctl_mboxlist -u < /tmp/foo
(check uid/gid of /var/lib/imap/mailboxes.db after import)
- run reconstruct
# reconstruct -r -V max user/whatever
Note that if you have user names with dots (e.g. foo.bar), you will
have to rename sieve folders from foo^bar to foo.bar
Hope it helps. I could have forgotten something, though.
Javier.

That's great thank you... I'll give it a try. You are correct, looks
like I missed some steps.
In the meantime I've been working to get sync_client / sync_server
working, and am making good headway there. I had to run reconstruct a
few times on the source, including with GUID corrections with -G and
-R, and had to delete a couple of emails completely, but have been
able to get a fully completed test replication of all users, so I am
also thinking that may be easier. Does replication bring over sieve
scripts?
I still have the following questions though:
1. How to set up squatter in rolling mode on 3.0.7.
2. Whether I need to do anything new for quota management
Incidentally - the "quota" utility is not present on my RHEL 8
install of Cyrus 3.0.7 - is this a known issue?
3. I have set altnamespace: 0 to match what I have on the old server -
will that retain the old behaviour? Any issues with migration, sieve?
Mailboxes appear to have replicated ok, including one with a dot,
which has a folder structure of name^name.
4. Is a "shutdown file missing, updating recovery stamp" message
normal on restart of cyrus-imapd
5. New question - after replication from 2.4 to 3.0 and once I have
stopped replication and am running with the new one, do I need to run
reconstructs on the 3.0 replicated mailboxes? e.g. -V max, etc.?
