Overview

After upgrading to Squirro 2.5.3, all dashboards using loaders will be broken and need to be fixed first.

The basic approach to upgrading is as follows:

1. Upgrade to Squirro 2.5.3
2. Right after the upgrade, convert any dashboards using a loader to using layers

The entire process is relatively quick, but it does require a maintenance window to ensure that users are not presented with non-functioning dashboards.
