Best approach to copy mailbox from one office 365 tenant to another

Copper Contributor

I am looking for best approach to copy mailboxes from one office 365 tenet to another.  I also checked the cross tenant migration approach but in this approach source mailbox will be disabled after completion of migration and 

Is there any other best and recommended method we can copy the mailboxes without deleting/disable the source mailbox? i have tried the export and import PST method but that is also slow process 

Thanks in advance

If you don't want to export/import you are going to have to purchase and use a 3rd party tool

You can take the help of the manual method for migrating Office 365 Tenant to Tenant. For this, you must have sound knowledge and lots of time. Because using a manual approach, you can migrate multiple mailboxes at once.
To migrate Office 365 Tenant to Tenant easily and securely, you can also choose Shoviv Office 365 Migration.

you can try open both in outlook profile and use drag n drop. This isn't more handy then PST I think.
I would use 3rd party or some Powershell script.
That is what i think so now, Thanks
