You will need to configure local Self-IP addressing yourself as the migration method you have shared is to create a new device service clustering (DSC) between the devices.

However, you can simply configure the VLANs and a single Self-IP to be used as the Config Sync address to get the configuration copied/synced over to the new device then break the DSC (making sure the new device is offline in some way) then take the Self-IP configuration from the 

bigip_base.conf
configuration file and do a configuration merge in TMSH.

Then you migration cut over can be to simply take the old F5 off-line (recommend off the network by shutting down the interfaces) and bring the new F5 BIG-IP online.

I also highly recommend looking at running the BIGdiff (https://devcentral.f5.com/codeshare/bigdiff-1160) tool to assist with checking the status of Virtual Servers and Pools etc during the migration.
