I updated the Sugar instance hosted in the vagrant box on my localhost from 8.2 to 8.3 by 1) replacing all files and folders in the root directory with those from a backup of our production instance and 2) loading the MySQL dump files that were included in the backup into my local database. After I did that, I was able to log in and open the dashboards in the Home module with no problems. But when I try to go to the Admin page, I get a blank page with an error: "Sugar CRM 8.2.0 Files May Only Be Used With A Sugar CRM 8.2.0 Database". What are the possible reasons that would throw this error, considering that all the files and the database are from Sugar 8.3?
Thank you for any help!
