Is this issue completed?

[damiannolan]

Need to add a basic upgrade test that runs automatic migrations.

We can't actually reuse "normal upgrade" in simapp in its current state. For example, if we upgrade from v7.0.0 -> v7.1.0, then "normal upgrade" is already a registered upgrade handler and on x/upgrade begin block we fail here. We basically need to register the default upgrade handler against a new name in the v7.1.0 binary.

[colin-axner]

That makes sense. Essentially each upgrade/bin needs a unique name?

[damiannolan]

Yeah, we can reuse CreateDefaultUpgradeHandler but we need a unique name for each version increment.
