We are migrating from an AWS Windows server/environment to an AWS Linux server/environment.
-
The Matomo, MySQL, and PHP versions are the same for both source/target environments.
-
We copied/restored the source database to the target database, and all users, segments, goals, tracking failures, websites, plugins, and container counts match.
-
While simply doing a source/target side-by-side webapp screen comparison, in/on the Administration->Diagnostic->Database Usage page, in the Reports section, we see this error: “The unserialization has failed!”

The following related error is in the php/log file:
