Forum OpenACS Q&A: Response to Another (hopefully last) big OpenACS 4/PG datamodel change

Hi Don,

We have used OpenACS4 code pre change of tree sort keys.  Although
the sites are not very large there are some contents like news, cms,
file-storage.  We do have 1 site that has about a hundred users
already.

What would be the best way to upgrade the datamodel for this sites?

Do a pg_dump, reinstall with the new code, edit the pg_dump and
restore?

Or create custom export scripts, reinstall, use custom import
scripts?
