Test with real data
This is the final testing phase. In previous steps, the data that was migrated wasn’t real ‘end-user’ data. However, at this stage in the migration, it’s time to use real data.
A single end-to-end test is preferred.
Of course if the whole project involves migrating a single large journal archive, then it might not be possible to test something like that in its entirety. (So what can be done instead?)
What happens if these things aren’t working?
If some of the items on this list are not successful/adequate, try to isolate the issue(s) and resolve them.
