Issue

  • Is there any specific reason for not removing 'old unused' tables from the database after the upgrade? For example, Liferay Bookmarks were archived with no direct replacements in Liferay 7.3 but after the upgrade, 'BookmarksEntry' and 'BookmarksFolder' tables remain in the database.

Environment

  • Liferay DXP 7.3

Resolution

  • Liferay can not remove tables automatically during the upgrade because some users may want to continue using them. Tables can be removed when the data has been migrated to another place first (for example JournalArticleImage). So, Liferay is covering the removal of those tables in the Data Cleanup application. 

Additional Information

  • As always, before deleting this data either through the tool or manually, users must carry out a complete preliminary analysis in the respective environment and verify that they no longer make use of those specific portlets or related data. 
  • It is recommendable to make a database backup before executing the process.
