LocalConfiguration filled with default extConf values after Upgrade
I'm just upgrading a project from TYPO3 8 to TYPO3 9. After upgrading TYPO3s SourceCode I visit the TYPO3 Backend. But with this request the LocalConfiguration.php was updated silently. All my individual Configuration in extConf were thrown away and replaced with the default values of ext_conf_template.txt.
I mentioned this problem a little bit too late and started a new try to upgrade, but that time I visit the Installtool first. Now, the extConf values were transferred correctly into new EXTENSIONS key of LocalConfiguration.php.
Installtool calls "executeSilentLegacyExtConfExtensionConfigurationUpdateAction" which does the correct job.
First request to BE calls ExtensionConfiguration->synchronizeExtConfTemplateWithLocalConfigurationOfAllExtensions which creates EXTENSIONS key with default values. It seems that this line makes the problem:
$currentLocalConfiguration = $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS'] ?? ;

- Status changed from New to Needs Feedback
The issue stems from not following the upgrade guide: When upgrading TYPO3, after switching the source, go to the install tool and follow the steps here https://docs.typo3.org/m/typo3/guide-installation/master/en-us/Upgrade/UseTheUpgradeWizard/Index.html - opening the backend before running upgrade wizards, database compare and silent upgraders might result in more weird behaviour otherwise (or a broken installation).
Can you confirm that the problem does not occur when following the upgrade guide?
