Hello @Shivani Saran and welcome to Atlassian Community :)
If you're seeking for an easy way to clone an issue across projects including form submission details, I suggest trying our app Elements Copy & Sync that allows you to clone and sync a full hierarchy of issues with all their content (summary, description, custom fields, comments, attachments, etc).
You can check our guide here.
The app is for free during 30 days (and it stays free under 10 users).
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
