Diff for MigrateIdentities between 3 and 4

+ Migrating identities



ThisThis is a small !MySQL script that migrates email addresses and full names from old IMP 2 databases to the identity arrays used in Horde 3/IMP 4. By tweaking the sub-select statement, you can use the same script to migrate existing user data from any external source.

 Please adapt it to your needs before running it.

<code type="sql">

INSERT INTO horde_prefs

    (pref_uid, pref_scope, pref_name, pref_value)

    SELECT

        SUBSTRING(user, 1, LOCATE('@', user) - 1),

        'horde',

        'identities',

        CONCAT('a:1:{i:0;a:5:{s:2:"id";s:16:"Default Identity";s:8:"fullname";s:',

               LENGTH(IFNULL(fullname, '')), ':"', IFNULL(fullname, ''),

               '";s:9:"from_addr";s:', LENGTH(IFNULL(replyto, '')), ':"', IFNULL(replyto, ''),

               '";s:16:"default_identity";s:1:"0";s:9:"signature";s:', LENGTH(IFNULL(sig, '')), ':"', IFNULL(sig, ''), '";}}')

        FROM imp_pref WHERE user LIKE '%@localhost' OR user LIKE '%@example.com';

</code>



This code takes all entries from the {{imp_pref}} table that have the user name ending with {{@localhost}} or {{@example.com}}. This domain part is then stripped from the user name ({{SUBSTRING(...)}}) and a string representing a serialized PHP array is build ({{CONCAT(...)}}) from the {{fullname}}, {{replyto}}, and {{sig}} columns and inserted into the {{horde_prefs}} table. The {{IFNULL(...)}} expressions make sure that this works with both, empty and NULL values in the table fields.



Please note that this script only makes sense for //one-time// migration of existing data. If you have this kind of user data in an external source permanently, e.g. in a company addressbook, LDAP directory or similar, you should use preference hooks to create the user identities instead.
