Hello,

You would need to remove all sub task issue types from the issue type scheme for this project. You can read more about issue type schemes here:

Hello Alexey,

I am getting proxy error for this.

[Alexey Matveev]

Ok.

Basically go to the project settings -> Issue Type scheme. Then edit it, remove all subtask types and save.

In this case you will not have sub tasks anymore in your project. Jira will ask you to convert all existing sub tasks to a new issue type.

I am getting error.. I think sub-task is mandatory.

[Alexey Matveev]

Sub-tasks are not mandatory.

Write a JQL query like this in your Issue Navigator:

issuetype in subtaskIssueTypes() and project = yourproject

Then convert all selected issues to usual tasks by bulk edit. User the move option there. After it you should be able to remove the sub-task type from the issue type scheme.
