there are three steps to success on (drupal) moving day...

1. start with a fresh drupal installation photo: julishannon

2. be neat and tidy to avoid disaster later photo by: bringo

3. aim to have happy users at all stages of the move photo by: waderockett

What does it mean to move? 1. Assessing the databases 2. The Export 3. Preparing Drupal for the new content (CCK) 4. Import modules 5. Importing content “by hand”

1. Assessing the databases

examine your database what is the db software? is there a tool to export content? what formats can you export content to? how is your content stored in the database? do you need to move user accounts as well?

examine drupal’s db what content type(s) are you using? what are the tables you need to place content into?

` Using MySQL Command Line Magic

Drupal 5 tables

mysql> describe node; +++++++ | Field | Type | Null | Key | Default | Extra | +++++++ | nid | int(10) unsigned | NO | PRI | NULL | auto_increment | | vid | int(10) unsigned | NO | PRI | 0 | | | type | varchar(32) | NO | MUL | | | | title | varchar(128) | NO | MUL | | | | uid | int(11) | NO | MUL | 0 | | | status | int(11) | NO | MUL | 1 | | | created | int(11) | NO | MUL | 0 | | | changed | int(11) | NO | MUL | 0 | | | comment | int(11) | NO | | 0 | | | promote | int(11) | NO | MUL | 0 | | | moderate | int(11) | NO | MUL | 0 | | | sticky | int(11) | NO | | 0 | | +++++++ 12 rows in set (0.00 sec)

mysql> describe node_revisions; +++++++ | Field | Type | Null | Key | Default | Extra | +++++++ | nid | int(10) unsigned | NO | MUL | | | | vid | int(10) unsigned | NO | PRI | | | | uid | int(11) | NO | MUL | 0 | | | title | varchar(128) | NO | | | | | body | longtext | NO | | | | | teaser | longtext | NO | | | | | log | longtext | NO | | | | | timestamp | int(11) | NO | | 0 | | | format | int(11) | NO | | 0 | | +++++++ 9 rows in set (0.00 sec)

plan your move! write yourself notes describing the process cross off the steps as you complete them

2. Exporting useful data

export tools every database has its own export tool if you are exporting from MySQL use mysqldump export to CSV where possible (comma separated values)

exporting content: the dump http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html You can also use PHPMyAdmin if it’s installed! MySQL to MySQL ejhogbin@bilbo:~$ mysqldump u root p [dbname] > oldsite.sql MySQL to CSV (local machine only) ejhogbin@bilbo:~$ mysqldump u root p fieldsterminatedby=, tab=[outputdirectory] tables [dbname] [tablename] > table.txt Import into MySQL ejhogbin@bilbo:~$ mysql u root p [newdatabase] < oldsite.sql

3. Preparing Drupal for the new content (CCK)

Installing CCK modules (CCK, image, date, etc) creating content types

4. Import modules

Drupal import tools http://drupal.org/project/Modules/category/64 html_import, node_import and user_import importing from WordPress? I used wp2drupal (4.7); try wordpress_import

import_html modules: path, import_html in Ubuntu: sudo aptget install php5xsl (yes, even though it says XML support is enabled in the phpinfo() test file) review the settings (keep the defaults) copy the site to a local directory (use wget to generate a flat site if necessary) proceed with the import set the path to the local directory where your static site lives check “more settings” to set the user and default settings for each node play with XSL template file if necessary (and you feel like an XML pro) click “next” and choose the files to import click import check for errors enjoy your imported content

start page: import_html

choose what to import

choose the files to import

success! (I’m actually overwriting the initial import on this second attempt.)

node_import modules: node_import prepare your CSV file to import prepare your Drupal installation to receive the imported data proceed to: admin/content/node_import choose the CSV file that contains the data choose your content type (e.g. page or story) match the data in your CSV file to data run the import node_import runs on cron and may take several hours for very large amounts of content

upload your CSV file

match data to drupal fields

set node author

user_import basically the same as node_import upload your CSV file and match fields onto drupal’s database user profile data must be uploaded separately into nodes (ask me later, we’re probably running short on time)

passwords: oh the headaches if you’re lucky they’re stored as plain text in the other db if they’re encrypted hopefully it’s with MySQL’s md5() function drupal stores passwords with the md5() mysql function back up the user table and convert passwords from plain text to md5() mysql> create table users2 select * from users; mysql> update users2 set pass = md5(pass);

5. Importing content “by hand”

importing plain vanilla content 1. import the data into temporary tables 2. using the insert/select command copy the data into node and node_revisions 3. update the sequences table to show the next nid

importing CSV data mysql > create table tmpdata (tmpid int, key1 int, key2 int); mysql > load data local infile '/home/emmajane/data/data.csv' into table tmpdata fields terminated by ',' optionally enclosed by 'quot;' lines terminated by 'n' (tmpid, key1, key2);

create “story” node stubs mysql> insert ignore node (nid, vid, uid, title, type) select tmpdata.nid, tmpdata.nid, tmpdata.uid, tmpdata.pagetitle, quot;storyquot; from tmpdata;

insert the body/description into node_revisions mysql> insert ignore node_revisions (nid, vid, uid, title, body, timestamp, format) select tmpdata.nid, tmpdata.nid, tmpdata.uid, tmpdata.pagetitle, tmpdata.pagecontent, unix_timestamp(now()), 1 from tmpdata;

update sequences (v5) mysql> select nid from node order by nid DESC limit 1; ++ | nid | ++ | 18325 | ++ mysql> update sequences set id = 18325 where name = “node_nid”; mysql> update sequences set id = 18325 where name = “node_revisions_vid”;

SRSLY! Do not forget! Bad things happen when you fail to update sequences. photo by: croma

importing special content 1. import the data into temporary tables 2. using the insert/select command copy the data into node and node_revisions 3. copy special content into CCK tables 4. update the sequences table to show the next nid

CCK content use Drupal to create CCK tables examine the structure copy your content into the new tables

cck tables mysql> describe content_type_pattern; +++++++ | Field | Type | Null | Key | Default | Extra | +++++++ | vid | int(10) unsigned | NO | PRI | 0 | | | nid | int(10) unsigned | NO | | 0 | | | field_byline_value | longtext | YES | | NULL | | | field_intro_value | longtext | YES | | NULL | | | field_intro_format | int(10) unsigned | NO | | 0 | | | field_materials_value | longtext | YES | | NULL | | | field_finished_size_value | longtext | YES | | NULL | | | field_gauge_value | longtext | YES | | NULL | | | field_notes_value | longtext | YES | | NULL | | | field_notes_format | int(10) unsigned | NO | | 0 | | | field_contributor_nid_uid | int(11) | YES | | NULL | | +++++++

Moving Content Summary 1. Assess the situation and plan your move 2. Export content to a useful format 3. Create the new home for your content 4. Use the import modules OR 5. Importing content “by hand”
