Can the upgrade from 3.4.7 to 4.0 be automated?

[snugRugBug]

I'm in the process of designing a migration script, and I'm trying to automate as much of the process as possible. At the moment the flow is:

1. Import data to IPB 3.4.7 using the converter app

2. Upgrade IPB 3.4.7 to IPB 4.0

Would it be possible automate step 2? I'm guessing I will just need to run the right script with the right input...
