Upgrade xibo 1.6.4 to xibo 1.7.0

Hello,
I would have gone from xibo 1.6.4 to xibo 1.7.0 to finally upgraded to the latest version if possible but I have an error message

"An error occurred running the upgrade. Please take a screen shot of this page and seek help. Statement number: 80. Error Message = [SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name ‘version’]

Upgrading from database version 72 to 84

I agree I have a valid database backup and can restore it should the upgrade process fail

It is important to take a database backup before running the upgrade wizard. A backup is essential for recovering your CMS should there be a problem with the upgrade."

thank you for being able to help me

I would roll back to your backup of the database, and then upgrade straight to 1.7.10. From there you can upgrade to 1.8.11.
