In upgrade doc for 2.4, it is mentioned here that a some workflow tables needs to be added.

However, looking at the .sql file in question it also contains other tables you won't have if upgrading from eZ Publish Platform 5.4:

• ezflexworkflow
• ezflexworkflow_message
• ezdatebasedpublisher_scheduled_version

These tables are also missing if upgrading from 1.7

As far as I can see, there are no mention in the docs that these tables has to be created.

Table eznotification is also listed but that one is created during normal upgrade process due to the .sql linked to here

Creation of Page builder tables are linked to here

Creation of form tables are linked to here

Creation of workflow tables are linked to here

I haven't checked closely if the definition of the mentioned tables has changed as time passes by, but this seems to be at least one case of that : https://github.com/ezsystems/ezplatform-ee-installer/commit/f735d96ca668e19da90859d8b9a583a3c20837ff
As far as I can see there exists no upgrade scripts for such changes either

(Side node : I also notice that from 2.5, these schema definition has been moved from ezplatform-ee-installer to their corresponding bundle, which is good.)
