Hello all, I want to implement https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix on our instance, however from my understanding this will only prevent the problem from happening in the future, it will not fix the current corrupted data. I happen to have 19 ids that exist on both issues and old_issues and would like to the clean-up before going further. However, I'm not sure how to proceed: 1) Remove the 19 ids from the *issues* table and implement the fix. Downside is the data of those 19 issues would be lost and it would be as if those check-outs never happened; 2) Remove the 19 ids from the *old_issues* table and implement the fix. Data is lost, would be as if the item was never checked out and then checked in again but, in theory, this would open room for the 19 ids in the issues when they check-in. 3) Update the 19 ids in the *issues* table to the next 19 ID's available, move the AI value 19 upwards and check if it's +1 than the current max(issue_id). This is, in theory, the best way as no data is lost, those 19 ID's in *issues* table would have their ID's available in the old_issues table, and the fix prevents the problem from happening in the future. However this sounds the most risky way to go about it. Would anyone give me advice or their opinion on this? Am I looking at this the right way or is there some other better way to work around it? Thanks a bunch, Pedro Amorim
