Yes you are correct. You have to modify the user account settings with the Set-Mailbox cmdlet so that the account points to the mailbox on the new mailbox server. To move all of the users from the old database to the new database.

Wanna know I got failed to mount the old exchange database in new exchange server,  after I create the new mailboxes database together for the log and edb ( this edb do I need to create the same name as the old exchange edb ? ) location, I ran the overwrite command, and start to copy the old exchange edb and logs to the corresponding location of the new created mailbox database, and renamed the old edb file name back to the new edb file name, and mount it, it doesn't work, just wonder am I doing it correctly for the above steps ?

Also if the old exchange is in 2010 sp3 and the new exchange is running without any sp, will there be any problem of doing the database portability ?
