Error moving config file when upgrading Jahia



When upgrading a Jahia version, the upgrade fails with the following error if there are config files (*.cfg) under 'JAHIA_INSTALL/digitall-factory-data/modules' directory

2020-10-30 15:10:35.807> Error: Error while applying fix
java.io.IOException: Error executing script /home/jahia/.fixapplier/temp/resources/scripts/after_fix.groovy

As Jahia now uses Karaf to manage the modules configuration. The upgrade will try to copy all the config files which may exist in the 'digital-factory-data/modules' from old version to the new' digital-factory-data/karaf/etc' directory. This error happens due to a bug in the upgrade script as it fails to successfully copy the file.



The solution is to remove the the config files from the 'digital-factory-data/modules' directory and try the upgrade again.
