I would consider that a *very* last-ditch option. For SQL schemas, there
is often/usually a way to transform the old into the new. Take a look at
IRM for an example of how I did this for a fairly major set of changes.
What does upstream recommend for upgrades? I presume they don't advocate
"aah, just blow it all away and start again", do they?
