Attention
TYPO3 v7 has reached its end-of-life November 30th, 2018 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.
There is no further ELTS support. It is recommended that you upgrade your project and use a supported version of TYPO3.
Backup¶
Make a backup first! If things go wrong, you can at least go back to the old version. You need a backup of
all files of your TYPO3 installation (by using FTP, SCP, rsync, or any other method)
the database (by exporting the database to an SQL file)
Also you may prefer to upgrade a copy of your site first, if there have been a lot of changes and some of them might interfere with functions of your site. See the ChangeLog to check that.
