These are instructions to upgrade from earlier IMP versions. Please backup your existing data before running any of the steps described below. You can't use the updated data with your old IMP version anymore.
Upgrading IMP is as easy as running:
pear upgrade -a -B horde/imp
If you want to upgrade IMP with all binary dependencies, you need to remove
the -B flag. Please note that this might also try to install PHP extensions
through PECL that might need further configuration or activation in your PHP
configuration:
pear upgrade -a horde/imp
If you want to upgrade to an alpha or beta version of IMP, you need to tell the PEAR installer to prefer non-stable package versions. Please note that this might also install pre-release 3rd-party PEAR packages:
pear -d preferred_state=alpha upgrade -a horde/imp
If you want to upgrade from an IMP version prior to 5.0, please follow the instructions in INSTALL to install the most recent IMP version using the PEAR installer.
After updating to a newer IMP version, you always need to update configurations and database schemes. Log in as an administrator, go to Administration => Configuration and update anything that's highlighted as outdated.

The 'mbox_readonly' hook has been removed. Mailbox permissions can instead be controlled via native IMAP ACLs or, alternatively, by the 'mbox_acl' hook.
The 'mbox_special' hook has been removed. Additional special mailboxes can
now be defined per-backend in config/backends.local.php.

- getMaillog - getMaillogChanges - logMaillog

The 'namespace' option now requires the namespaces to be in the UTF-8 charset, not UTF7-IMAP.
The 'smtphost' and 'smtpport' options have been removed. They have been replaced by the 'smtp' option, which allows ALL available SMTP configuration options to be overriden.
The 'admin' option has been changed: optional configuration parameters should live within the base 'admin' array rather than a 'params' array within the base.
The $conf['fixed_folders'] option now requires the mailboxes to be in the UTF-8 charset, not UTF7-IMAP.
The $conf['compose']['link_attach_size_limit'] option was added.
The $conf['print']['add_printedby'] option was removed and replaced by the 'add_printedby' preference.

This is a non-exhaustive, quick explanation of what has changed between an IMP 4.x installation to IMP 5.x.

The dynamic view (DIMP) no longer supports the 'action' parameter located in config/menu.php.
Portal rendering has been moved to Horde - config/portal.php is no longer needed or used.
This is a non-exhaustive, quick explanation of what has changed between an IMP 4.1.x installation to IMP 4.2.x.
An SQL table has been added that can be used to track sent messages. This is necessary to provide users with the "favourite recipients" address book, and for message rate throttling.
Execute the provided SQL script to add the table to your database, e.g.:
mysql --user=root --password=<MySQL-root-password> <db name> < scripts/sql/imp.sql
Separate quota drivers for Cyrus and Courier servers are no longer
necessary. These drivers have been replaced by a generic IMAP driver that
should also be suitable for other IMAP servers that support the QUOTA
extension. Update config/servers.php and change the 'quota' => 'driver'
setting to 'imap'.
All hooks that are specific to IMP have been moved from the
horde/config/hooks.php file. Move your existing IMP Hooks from there to
imp/config/hooks.php.
The usage of the hook _imp_hook_mbox_icons() has changed. If you use this
hook, make sure you change your implementation so it returns the correct
value.
The default values for the mailbox preferences 'sent_mail_folder', 'drafts_folder', and 'trash_folder' have been changed and localized. Use the old values to prohibit the creation of duplicate mailboxes for users that didn't explicitly set the mailboxes in their preferences.
The following preferences are no longer used and may be safely removed from
your config/prefs.php file and your preferences backend:
'auto_expand' 'num_words'
The 'mail_hdr' preferences has been moved from the identities to a regular preference. Existing user preferences are no longer used and have to be re-created by the users.
The new hook _imp_hook_msglist_format() has been added which allows the
formatting of a message entry in the mailbox message list to be altered
at the time the list is created. This hook has made the following
configuration options obsolete:
$conf['mailbox']['show_attachments'] $conf['mailbox']['show_xpriority']
If you wish to continue using the functionality previously provided by these
options, you should activate the msglist_format hook in config/conf.php.
The sample hook contained in config/hooks.php contains the code necessary
to replicate the previous behavior.
The pspell driver is no longer supported since it does not work with
HTML messages. If using pspell, you must upgrade to aspell version 0.60+.
Support has been added for FCKeditor as an option for the javascript HTML editor available on the compose page. You must have Horde 3.2 or later installed to use this editor.
This is a non-exhaustive, quick explanation of what has changed between an IMP 4.0.x installation to IMP 4.1.x.
The namespace, hierarchies, folders, delimiter, and
dotfiles parameters were removed from config/servers.php. Namespaces
are now automatically configured pursuant to RFC 2342.
If using the UW IMAP daemon, you may notice a bunch of additional namespaces that were not displayed before as well as the ability of the user to view all files that live in their home directory via the folders screen. Information on how to correct your IMAP server configuration can be found at
http://wiki.horde.org/ImpUWIMAPNamespaces
The config/headers.txt file has been removed and replaced by
config/headers.php. Any user-defined headers should be migrated to this
file. The new file has the advantage of allowing any valid PHP expression
to be executed at run-time when generating the headers. See the top of
the headers.php file for the new format required.
The following preferences are no longer used and may be safely removed from
your config/prefs.php file and your preferences backend:
'disposition_request_delivery' 'wrap_width'
The format for saved Virtual Folders has changed. To convert to the new
format you must run the script located at
scripts/upgrades/convert_vfolders.php.
