Hi Lorill This is known issue with older versions of DHIS 2 (it was a serious bug in hibernate, which we use as our ORM layer).
Jason created a script that will add them back (but please know that there might be conflicts, as uniqueness constraints are added) I'm adding him in, as I don't have access to that script right now.. he can hopefully share it -- Morten On Thu, Jul 23, 2015 at 4:22 AM, Lorill Crees <lcr...@2paths.com> wrote: > Hi, > > We've noticed that many of our databases that have been upgraded from 2.18 > to 2.19 and then to 2.20 are missing many of the unique constraints that > are present when creating a 2.20 database from a new install.
