I'm curious how this user change the type to a sub-task since that it's not possible. Adding something to what Bhushan said what you can do it's to create the new issue type and then move all the issues from the wrong type to this new one, so then you can delete the type without losing anything and without taking the risk of modifying the DB.
Oh ok I see what you are saying. The issue type itself.
Firstly I am not sure you you managed to change that since I don't think there is a UI to change Issue Type from Standard to Subtask.
You can change it in the database but make sure you try this in a test environment.
UPDATE jiraschema.issuetype SET pstyle='jira_subtask' where pname='Unit Test Solution'
If you do not have any issues assigned to it yet, simply delete and recreate as a Subtask issue type
Hmm, in that case, he's describing something Jira does not do. You can't change an issue type between parent and child. The closest I can think of is that you rename <sub task> to "fred", then rename a <top level type> to <what the sub task was> then rename <sub task fred> to <what the top level type was called before>
