I found the Doc on moving from a v7.1.x -> v7.2.x database (
https://openacs.org/doc/misc/openacs-pg-migration.txt), but, in the case presented in a previous thread, my client's issue appears to be that the OpenACS 4.x installed for him (from Apr 9th, 2002) isn't new enough to handle the v7.2.x database ...
Is there a doc on how to upgrade the OpenACS environment itself, that someone can point me to?
