Statement from Kunagi Team
Downgrades never work! This is because newer versions of Kunagi use new (extended) data formats.
You have to do a data backup on 14.1. Then upgrade to 16.1. If you would like to go back to 14.1, you have to restore the backup.
To create a backup, you have to copy/zip the whole data directory. On startup, the log file shows, which directory is used as the data directory. It contains folders like
backup directory inside of the data directory is a backup for internal Kunagi use. Not a backup of your project data.
To restore your backup, you have to copy/unzip it back to where it was. Make sure, that you delete the destination directory, before restoring. If you just overwrite, things might mess up.
Issue is closed.

I would highly recommend to always use the newest version. If you have a problem with the newer version, please let us know. Since we release nearly every month, chances are good, we fix your bug.

You have to ignore the
backup directory. It is for internal use only and not relevant here.
- Install Kunagi 1.6.
- Start Tomcat.
- Look into log file, to see the used data directory.
- Stop Tomcat.
- Delete the
entitiesdirectory from the data directory.
- Put the
entitiesdirectory from your backup there instead.
- Start Tomcat.
