I'm in the middle of an upgrade from 2010 to 2013, and I'm running into an issue when attempting to upgrade one of my content databases using PowerShell. The content databases attached to my other web applications have mounted fine, but this particular one is presenting issues.
The error I'm receiving is as follows:
Mount-SPContentDatabase : The DELETE permission was denied on the object 'TVF_Features_PK', database 'MyContentDB', schema 'dbo'.
I've given the account that I'm using to execute to PS command db_owner permissions on the database, but that doesn't seem to be helping. Any thoughts?
