Migration from tt_news to news

This tutorial will help you to migrate data from tt_news to news.

Requirements

  • Installed extension news
  • Installed extension news_ttnewsimport

Hint

If you experience any troubles during imports, test the latest versions of the 2 extensions which can be found at https://git.typo3.org/TYPO3CMS/Extensions/news.git and https://github.com/fsaris/news_ttnewsimport.

Migration

Migration of records

To be able to migrate records, you need to activate the import module. This needs to be done in the configuration of EXT:news inside the Extension Manager.

  1. Activate the checkbox “Show importer”, save and reload the backend. Now you should see the backend module “News Import”.
  2. Switch to the backend module.
  3. Select “Import tt_news category records” from the select box and start the import of categories.
  4. Select “Import tt_news news records” from the select box and start the import of news records.

Migration of plugins

The plugins of tt_news can be migrated to plugins of EXT:news as well. This is done by using the CLI:

./typo3/cli_dispatch.phpsh extbase ttnewspluginmigrate:run
./typo3/cli_dispatch.phpsh extbase ttnewspluginmigrate:removeOldPlugins

Read more about the migration and its limitation in the documentation of news_ttnewsimport at https://github.com/fsaris/news_ttnewsimport.

Migration of unique aliases

If a lot of similar titles are used it might be a good a idea to migrate the unique aliases to be sure that the same alias is used.

# temporary table
CREATE TABLE tx_realurl_uniqalias_migration LIKE tx_realurl_uniqalias;
# copy
INSERT INTO tx_realurl_uniqalias_migration SELECT * FROM tx_realurl_uniqalias WHERE tablename='tt_news';
# fix it
UPDATE tx_realurl_uniqalias_migration SET value_id = (SELECT tx_news_domain_model_news.uid FROM `tx_news_domain_model_news` WHERE tx_news_domain_model_news.import_id=tx_realurl_uniqalias_migration.value_id),tablename='tx_news_domain_model_news' WHERE tablename='tt_news';
# remove wrong alias (news which have not been imported)
DELETE FROM tx_realurl_uniqalias_migration WHERE tablename='tx_news_domain_model_news' AND value_id=0;
# insert alias back into realurl table
INSERT INTO tx_realurl_uniqalias (tstamp,tablename,field_id,value_alias,value_id,lang,expire) SELECT tstamp,tablename,field_id,value_alias,value_id,lang,expire FROM tx_realurl_uniqalias_migration

Not migrated

Be aware that some things are not migrated:

  • Templates
  • TypoScript configuration
  • Backenduser & -group configuration
  • Additional fields added to tt_news by 3rd party extensions
