Upgrade from LTS to LTS

This chapter provides in depth information about how to update from TYPO3 6.2 LTS to the TYPO3 CMS 7.6 LTS version.

This chapter will give you a perspective on relevant changes since TYPO3 6.2 and what to expect from the migration from 6.2 to 7.6.


  1. TYPO3 Version

    Make sure your installation is running at least TYPO3 6.2 LTS. The TYPO3 7.6 upgrade process is possible from version 6.2 - not from older versions.

    If you are running a lower version of TYPO3, please upgrade to 6.2 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 compatibility6 from TER, is not necessarily needed. It provides a compatibility layer for extensions, which are compatible with TYPO3 6.2, but not yet with TYPO3 7.6, e.g. because they are still using old class names. If you are not using such extensions, you do not need to install the compatibility6 extension.
  • The upgrade wizard, which install the mediace extension, makes sure that the Media Content Element still is available in your installation. If you have not used this Content Element and if you do not want to use it in the future, you do not need this extension. Otherwise install it!

After the Upgrade

When you insert content elements into your website, you have the content elements "Regular Text Element", "Text & Images" and "Images Only". These content elements are provided by the extension css_styled_content.

In TYPO3 CMS 7, a replacement called fluid_styled_content is available. If you install this extension instead of css_styled_content, other content elements will be available, namely the one called "Text and Media". With this content element, you can combine text with any type of media, e.g. a PDF file, a video or an image. fluid_styled_content has the advantage that Fluid templates can directly be edited to influence rendering; it is not necessary to write TypoScript rendering definitions. Note however that some options no longer are available in fluid_styled_content, e.g. image processing options. If you use fluid_styled_content, your old content elements can be/have to be migrated to it.

Note that fluid_styled_content is in an early phase. At this time it is no problem to continue using css_styled_content. If and how fluid_styled_content will replace css_styled_content is not clear.
