Error opening BPC 7.0 SP7 Appset after restore to BPC 7.5 SP3 patch 3

We get the following error after restoring a server manager backup of a BPC 7M SP7 application set to a BPC 7.5 SP3 patch 3 server when we log into the admin client:

I am guessing that the admin client is executing a query that expects a database table in a certain format. Any thoughts on why this is happening? Admin client dies at this point with a message to look at Log ID:<number>

In the above code, I have removed internally-identfiable information about the name of the server, customer name, etc.
