Upgrade from LTS to LTS

This chapter provides in depth information about how to update from TYPO3 7.6 LTS to the TYPO3 CMS 8.7 LTS version.

This chapter will give you a perspective on relevant changes since TYPO3 7.6 and what to expect from the migration from 7.6 to 8.7.

Precondition

  1. TYPO3 Version

    Make sure your installation is running at least TYPO3 7.6 LTS. The TYPO3 8.7 upgrade process is possible from version 7.6 - not from older versions.

    If you are running a lower version of TYPO3, please upgrade to 7.6 first.

LTS Upgrade Process

Do the upgrade as described in the previous chapter. When you use the "Upgrade Wizards" note the following:

  • The upgrade wizard, which installs extension compatibility7 from TER, is not necessarily needed. It provides a compatibility layer for extensions, which are compatible with TYPO3 7.6, but not yet with TYPO3 8.7, e.g. because they are still using old class names. If you are not using such extensions, you do not need to install the compatibility7 extension.
  • The upgrade wizard, which migrates css_styled_content/fluid_styled_content allows parallel installation of both extensions in the system, making it possible to smoothly migrate from the now deprecated css_styled_content to fluid_styled_content.
  • The extension form_legacy contains the old form content element. The complete form element was replaced by a new form builder in the TYPO3 backend. If you are currently using forms, you should install form_legacy - and think about migrating your forms to the new extension.
  • The extension rtehtmlarea contains the old rich text editor which was replaced by ckeditor. Before installing you should check whether the new editor is already fulfilling all your requirements. ckeditor is easier to configure and runs smoother.
