Sorry, but you cannot selectively update modules from one version to another.
You need to update the complete source tree.

For instance, imagine that dbaccess depends on some code in, say, svtools. Now
if svtools changed incompatibly between m223 and m226, then the m226-version of
dbaccess will care for this. If you *only* update dbaccess, but not svtools,
then your source tree is inconsistent. The only change is to also update svtools
to m226.

However, now imagine dbaccess depends on something else. Or svtools depends on,
say, vcl, which depends on tools ...
Building the transitive closure here :) will prove that you need to update the
*complete* source tree, not only selected modules.

close issue.
