Upgrading From Previous Versions
Upgrading from 2.1.3 or earlier
* If you use notifications (previously notify_zephyr or notify_unix)
this functionality has been seperated out to notifyd. See the
notifyd manpage and example entries in master/conf.
Upgrading from 2.1.2 or earlier
* Sieve has been updated to be compliant with RFC 3028 and
draft-martin-sieve-notify-01. All notify actions and any fileinto
and/or redirect actions using stringlists will have to be
updated/changed.
Upgrading from 2.1.1 or 2.1.0
nothing known
Upgrading from 2.0.16 or earlier
* You must install and configure Cyrus SASL version 2 to use Cyrus
IMAP 2.1. You can download SASL at
http://asg.web.cmu.edu/cyrus/download/.
* If you use timsieved to manage Sieve scripts, and have enabled the
alternate namespace and/or the Unix hierarchy separator, run the
script "tools/translatesieve". This script will translate the
folder names in fileinto actions.
* Cyrus now uses the service name "sieve" instead of "imap" for the
SASL profile of timsieved. If you use timsieved to manage Sieve
scripts, be sure to update your password checking mechanism
appropriately,
* If you have enabled the improved directory hashing scheme, run the
script "tools/rehash full". This script will rehash your existing
directories.
* The hashed deliver databases (used for duplicate delivery
suppression and Sieve) have been merged into a single deliver.db
database. You can safely remove the entire /var/imap/deliverdb
directory structure after shutting down the server.
* All of the Cyrus databases have been unified under a single DB3
environment. A new ctl_cyrusdb tool is now used for database
recovery and checkpointing instead of ctl_mboxlist and ctl_deliver.
You should replace the appropriate START and EVENTS entries in
cyrus.conf with those in the sample configurations in the
master/conf directory.
* Cyrus now caches SSL/TLS sessions in an external database. If you
have support for SSL/TLS, and haven't disabled session caching (see
imapd.conf(5)), you should add a line like the following to the
EVENTS section of cyrus.conf to prune expired sessions from the
database:
# this is only necessary if caching TLS sessions
tlsprune cmd="tls_prune" period=1440
Upgrading from 2.0.6, 2.0.7, 2.0.8, or 2.0.9 or earlier
* If you use timsieved to manage Sieve scripts, run the script
"tools/upgradesieve". timsieved now uses symlinks instead of hard
links.
Upgrading from a previous 2.0 version to 2.0.6
Warning: You do not need to follow these instructions if you're
upgrading from version 1.6.
* You can now pick whether to use Berkeley db to store seen state,
the subscription files, and the mailboxes file or a flat text file,
at compile time only. (Look in imap/seen_db.c and imap/mboxlist.h.)
* The format of the mailboxes file and seen state has changed. It is
not possible to preserve seen state, but upgrade the mailboxes file
as follows:
1. Run ctl_mboxlist -d > mboxlist.temp to dump existing mailboxes.
2. Remove old database files: rm mailboxes.db db/* user/*/*.seen
3. With the new version of ctl_mboxlist, run ctl_mboxlist -u <
mboxlist.temp.
Upgrading from 1.6.22 or 1.6.24
Warning: Cyrus imapd 2.0 will automatically convert on-disk file
formats as the server is used. It is not possible to run 1.6 after 2.0
has been used on a mail spool without reconstructing every mailbox.
* Create some extra directories and remove the duplicate delivery
database:
mkdir /var/imap/db
mkdir /var/imap/socket
chown cyrus /var/imap/db /var/imap/socket
rm -rf /var/imap/deliverdb
* Convert mailboxes file to Berkeley DB:
su cyrus
cd /var/imap
ctl_mboxlist -u < mailboxes
ctl_cyrusdb -c
Please keep a backup of your mailboxes file. You can dump an
old-style mailboxes file by using ctl_mboxlist -d.
* remove "/etc/inetd.conf" entries. The imap and popd3d lines need to
be removed from /etc/inetd.conf and inetd needs to be restarted.
* master process configuration: You'll need to configure the master
process Cyrus process and ensure that it starts on boot. see this
section of the configuration instructions.
* MTA configuration. You will have to reconfigure your MTA to speak
to lmtpd. See this section of the configuration document.
* cyrus.seen conversion. The cyrus.seen file will be automatically
upgraded as users read mail. After some time, you might want to
delete the cyrus.seen file in each mailbox; it is superceded by the
user/joe.seen file.
* cyrus.index conversion. The cyrus.index file will be automatically
upgraded the first time each mailbox is SELECTed.
* Netnews conversion. The netnews programs are no longer built. If
you are using netnews, you will need to apply the diff in the
netnews/ directory to INN or see if INN is now distributing those
changes. You will also want to run remotepurge on a regular basis
to purge old netnews posts.
Upgrading from 1.6.13
* Upgrading from the Cyrus IMAP server version 1.6.13 or earlier: if
you use Sieve, you should run the "tools/upgradesieve" script, as
the format of the "/usr/sieve" directory has changed slightly.
timsieved, included in this release, will handle maintenance of
Sieve scripts.
* Upgrading from the Cyrus IMAP server version 1.6.10 or earlier: if
you export news via the IMAP server, you'll have to change your
"newsfeeds" file to contain
collectnews!:*:Tf,WR:collectnews
The format of the input to collectnews has changed.
Duplicate delivery suppression is now required for Sieve.
* Upgrading from the Cyrus IMAP server version 1.6.1 or earlier
(including 1.5.x!): the quota and user directories are now hashed
by the first character of the username. This is to reduce the
number of entries in any given directory. It doesn't do a great job
(and in some cases it will do a really poor job) but as a quick
hack it shouldn't make things worse. Optionally, the data
partitions can also be hashed by enabling the "hashimapspool"
option.
You must hash your directories using the "dohash" script in the
tools subdirectory. (If you want to hash your mail spool, be sure
to set "hashimapspool" before running "dohash".) This must be run
as the Cyrus user. Be sure to stop mail service while converting.
Doing this in single user mode is probably the safest.
Upgrading from 1.5
* Upgrading from the Cyrus IMAP server version 1.5 or earlier:
libsasl is now required. Configuring SASL to work may be a chore,
especially if you use shadow passwords.
* An ANSI C compiler is now required. gcc should work fine and can be
acquired from http://www.gnu.org/software/gcc/gcc.html.
* Make sure to read the upgrading instructions under 1.6 above.
* Upgrading from 1.5.14 or earlier requires deleting the delivered
database. Remove the file delivered.db in the configdirectory and
make a directory called "deliverdb" in the configdirectory. This
may cause some duplicates to get through.
* Upgrading from 1.5.14 or earlier requires removing the PTS cache
database (if the AFS PTS group support is used, which is not the
default). The PTS cache is in /var/ptclient/ptscache.db, and you
should remove it. This is because the format for the PTS cache for
IMSP has changed. If you use AFS ACLs, IMSPd, and IMAPd on the same
machine, make sure you have version 1.5a5 of the IMSP server for
this version of the IMAP server. (If you don't have IMSP, or AFS,
don't worry about it.)
