MODSOURCE-666 - Getting issue details... STATUS
if 999 ff s UUID is different from matched_id and status ACTUAL - get highest generation for matched_id and overwrite matched_id to be the same as 999 ff s with incremented generation and also If more than 1 ACTUAL record with the same matched_id - then to those records status will be set as 'OLD'.
The outlined scripts are targeted at fixing records on the Orchid version.
The scripts implementation aimed at the Poppy version is currently in the testing stage and will be described later.
1. Update records containing inconsistent matched_id with generation and state
Update unmatched matched_id and generation and update status
