src should be a SELECT, dst should be an INSERT.

Also, use explicit column lists in both the src and dst statements.

What makes you think they are excluded? The ones which IBO can't convert
are marked =UNASSIGNED or =SKIPPED

Base: means that there won't be (can't be) any conversion on the
data. Those columns would be blobs.

The Insert statement in the dst will fix it.
