If you want to update erp, you should use bench update --upgrade instead of bench init

Sorry for inconvenience,
Actually i was trying to install fresh erp and then i had plan to restore the database from version 6.
When I try to create a bench using bench init frappe-bench while installing, I got above error.

I don’t think your v6 database will work out of the box with v8. I think you will need to go sequentially through the versions ie v6 --> v7 --> v8. That way, all of the changes to the database schema will be applied to your database and your database will not be left in an unusable state.

Also note that when upgrading, it is a very good idea to backup your database and copy it to a safe location. In fact, it’s a must :smile:
