It's a 10g DB feature, not an ASM feature, so no, it doesn't require ASM. Regular filesystem files can be migrated just the same as ASM storage. In fact, for most people, migrating filesystem files is probably quite a bit easier :).

So, to follow your recommendation, wouldn't he also have to add a step to migrate from file-system to ASM after upgrading to Oracle10g? Not a trivial undertaking... ...2 more pesos....

If it's got any significant size, I'd consider upgrading to 10g on HPUX, then use transportable tablespaces to Solaris/10g. Just my 2 pesos.
