Does OpenEdge has an upgrade history, i.e. the dates when conv910, conv1011 were executed to the database?
In Oracle I query dba_registry_history view:
select action,
to_char(action_time, 'DD-MON-YYYY HH:MI:SS AM') upgrade_date,
comments source_version,
version target_version
from dba_registry_history where action = 'UPGRADE';
UPGRADE 11-OCT-2008 03:40:55 AM Upgraded from 9.2.0.4.0 to 10.2.0.4.0
UPGRADE 12-JUN-2010 02:29:06 PM Upgraded from 10.2.0.4.0 to 11.2.0.1.0
UPGRADE 31-MAR-2016 12:37:36 PM Upgraded from 11.2.0.1.0 to 11.2.0.4.0
So I can see that I upgraded version 9 to 10 on 11-OCT-2008
10 to 11 on 12-JUN-2010, etc ...
It should not be that difficult to record all proutil -C conv dates.
afaik, it does not. one would hope it would be recorded when keyevents are enabled, but alas it does not
