Yup, this is correct. That random characters is your transfer ID so note it down CAREFULLY.

Oh a bit warning: Check and double check your internet connection before you transfer. A single dumb glitch could kill the transfer. This is a one way process so if your internet crapped in the middle of process then it almost impossible to recover it.

Also in relation to that, make sure your new device COULD run CC. Again this is one way process and your could only use the password once. Once you initiated it, you can not use the password anymore so if your new device suddenly lags or error or anything stupid happened in the middle of loading your old acc then say goodbye to that acc.

There is a way to recover manually your account but that involved writing a nice long explanation email to Sega support IN JAPANESE. So yeah, do your homework before you do this.
