While permissions are important, a database upgrade is less likely to immediately break existing system-level permissions for a report service compared to affecting the direct database connection itself.

Changing the refresh rate is a display or performance setting and will not resolve an underlying connection error that prevents data from being displayed at all.

A database upgrade can alter connection strings, user credentials, network configurations, or driver compatibility, directly impacting the report's ability to communicate with the database. Verifying the connection ensures that the reporting service can still establish a valid link to the upgraded database, which is fundamental for data retrieval.

Checking data structure modifications is a valid next step if the connection is confirmed, but it's secondary to ensuring the report can actually reach the database post-upgrade.
