<li><strike>Policyd/Cluebringer database. It stores white/blacklists records, greylisting records, etc.</strike> Note: Policyd/Cluebringer were removed since iRedMail-0.9.3.</li>
<li>Basic info of in/out emails are stored in SQL tables: <code>maddr</code>, <code>msgs</code>, <code>msgrcpt</code>. Quarantined emails are stored in <code>quarantine</code>, it requires other 3 tables. If you don't have any quarantined emails, it's safe to delete all records in these 4 tables.</li>
<li>There might be some changes in LDAP schema, please find scripts <ahref="https://bitbucket.org/zhb/iredmail/src/default/extra/update/">here</a> to apply all required changes.</li>

<h2id="mysqlpostgresql-migrate-mail-accounts">MySQL/PostgreSQL: Migrate mail accounts</h2>
<p>All mail accounts are stored in database <code>vmail</code> by default, to migrate mail
accounts, you can simply export this database on old server, then import it
on new server.</p>
<p><strong>IMPORTANT NOTE</strong>: iRedMail-0.8.7 drops several SQL columns, so before you
import backup SQL database, please add them first. It's safe to drop them
after you imported old database on new server.</p>
<pre><codeclass="mysql">mysql> USE vmail;
mysql> ALTER TABLE mailbox ADD COLUMN bytes BIGINT(20) NOT NULL DEFAULT 0;
mysql> ALTER TABLE mailbox ADD COLUMN messages BIGINT(20) NOT NULL DEFAULT 0;
mysql> ALTER TABLE domain ADD COLUMN defaultlanguage VARCHAR(5) NOT NULL DEFAULT 'en_US';
mysql> ALTER TABLE domain ADD COLUMN defaultuserquota BIGINT(20) NOT NULL DEFAULT '1024';
mysql> ALTER TABLE domain ADD COLUMN defaultuseraliases TEXT;
mysql> ALTER TABLE domain ADD COLUMN disableddomainprofiles VARCHAR(255) NOT NULL DEFAULT '';
mysql> ALTER TABLE domain ADD COLUMN disableduserprofiles VARCHAR(255) NOT NULL DEFAULT '';
mysql> ALTER TABLE domain ADD COLUMN defaultpasswordscheme VARCHAR(10) NOT NULL DEFAULT '';
mysql> ALTER TABLE domain ADD COLUMN minpasswordlength INT(10) NOT NULL DEFAULT 0;
mysql> ALTER TABLE domain ADD COLUMN maxpasswordlength INT(10) NOT NULL DEFAULT 0;
mysql> ALTER TABLE alias ADD COLUMN islist TINYINT(1) NOT NULL DEFAULT 0;
</code></pre>
<p>After imported backup SQL databases, please execute below commands to mark
mail alias accounts and drop above newly created columns:</p>
<pre><codeclass="mysql">mysql> USE vmail;
mysql> UPDATE alias SET islist=1 WHERE address NOT IN (SELECT username FROM mailbox);
mysql> UPDATE alias SET islist=0 WHERE address=domain; -- domain catch-all account
-- Store values into new column: domain.settings and drop them
mysql> UPDATE domain SET settings='';
mysql> UPDATE domain SET settings=CONCAT(settings, IF(defaultlanguage IS NULL OR defaultlanguage='', '', CONCAT('default_language:', defaultlanguage, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(defaultuserquota IS NULL OR defaultuserquota=0, '', CONCAT('default_user_quota:', defaultuserquota, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(defaultuseraliases IS NULL OR defaultuseraliases='', '', CONCAT('default_groups:', defaultuseraliases, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(minpasswordlength IS NULL OR minpasswordlength=0, '', CONCAT('min_passwd_length:', minpasswordlength, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(maxpasswordlength IS NULL OR maxpasswordlength=0, '', CONCAT('max_passwd_length:', maxpasswordlength, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(disableddomainprofiles IS NULL OR disableddomainprofiles='', '', CONCAT('disabled_domain_profiles:', disableddomainprofiles, ';')));
mysql> UPDATE domain SET settings=CONCAT(settings, IF(disableduserprofiles IS NULL OR disableduserprofiles='', '', CONCAT('disabled_user_profiles:', disableduserprofiles, ';')));
mysql> ALTER TABLE domain DROP defaultlanguage;
mysql> ALTER TABLE domain DROP defaultuserquota;
mysql> ALTER TABLE domain DROP defaultuseraliases;
mysql> ALTER TABLE domain DROP minpasswordlength;
mysql> ALTER TABLE domain DROP maxpasswordlength;
mysql> ALTER TABLE domain DROP disableddomainprofiles;
mysql> ALTER TABLE domain DROP disableduserprofiles;
