Yes that is likely. I would recommend to
- make a backup of your database (export as zolca)
- install openLCA 1.6
- open and update the database
- validate the database (a new feature available in 1.6)
If there are any issues with the database, they will be shown (like: incorrect parameter formulas for example), and you can address them.
