# 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.)
