Unable to delete a ddmtemplate

Hi, there!I'm currently using Liferay Portal Version 7.1.3-GA4  and I'm experience a problem which has been reported for previous versions as well. This is the scenario: I create a custom structure, then a create a web template for this structure and finally I create a journal article. At some future moment I delete this article and try to delete the web template but then I get this error message "Error:The template cannot be deleted because it is required by one or more template links.". I check all the content in backend but there is no article using this template, Trash is empty as well. However, when I search my database I see tracks of  this template id, in ddmtemplate and ddmtemplatelink tables for example. An important detail that I should mention is that my database was upgraded from lower Liferay version 7.1.2-GA3 to 7.1.3-GA4 and my structure, template and journal content were created before the update. Is it possible some old content versions that are linked with the target template were saved in the database but were not deleted unlike the last published version of the article?
Regards,
Eli

1) Did you check the recycle bin? If the article is in the recycle bin, you can't delete the template
2) Please note that if you change an article and set a new template, old versions of the article might still reference that template
While 2) might not be too common, it happened a couple of times during development to us.

Hi, Christoph!Thanks for the reply! Yes, I think it is more likely the second case. Just the idea is how to manage this, because with deleted articles I think that the only option  for now is to clear the database tracks manually. Or at least this is the only option until Liferay devs change this behavior.

Ok. So you have added a new template for existing content. Well, you either need to could click through all articles and remove the old article versions (in the history) or you can use a script to do that. It depends, how many articles you have.

Last time I had a similar issue, I used the server console to fetch all articles using JournalArticleLocalServiceUtil and check the ddmTemplate. Then I simply deleted the old versions using a script.
