I need to migrate mails from one office 365 outlook mailbox to another office 365 outlook mailbox of same tenant. 

I also tried it from here,  https://answers.microsoft.com/en-us/msoffice/forum/msoffice_o365admin-mso_exchon-mso_o365b/migrating... and the status is success but when checked on the mailboxes no migrated mails where found. Please help.

Easiest way is to export/import via PST. You cannot do it server-side, at least not in an acceptable manner.
But the above method got completed for me the thing is in the new mailbox I cant see any migrated mails from old mailbox.
Hello @thuvaragesh,
It seems like you are looking for tenant-to-tenant migration in Office 365. We all know that Office 365 has different users and admin account for easy organization of emails. As you want to migrate your emails from one Office 365 users account to another user's account. I suggest you use any good professional solution. Since it is difficult to perform tenant-to-tenant migration manually in Office 365. Hence it is advised to use Office 365 Backup & Restore Tool to migrate emails within Office 365 account or export emails to other email clients. Also, you can restore OST & PST email files into your Office 365 admin & user account. You can try this tool from here:
