Data Management export and import for 1.2.x -> 1.3.x ... do I really have to?

[Wendy Smoak]

I've got a dozen Continuum instances to upgrade and I'm not really
looking forward to the process of exporting, importing and then fixing
the next available key values in each one of them.

ISTR someone (Brett?) saying that the only problematic change is a new
column that is required and has no default value.

Can anyone confirm or deny?  If it's true, which one is it and what
would I need to modify in a 1.2.x database to make it usable with
1.3.1?

Here's the diff of continuum.xml between 1.2.3 and 1.3.1:
