You can do it two ways:
1- Backup and restore:
- Backup the flash on the 650
- copy the flashbackup.tar.gz file off of the 650 controller
- copy the flashbackup.tar.gz file to the 3200 series controller
- execute the backup restore on the 3200 series controller (do not reboot)
- paste in the licenses for the 3200 (you cannot reuse the 650 licenses)
- reboot without saving
- You will still have to console into the 3200 and fix the interface configuration, because the 650 interfaces do not match the 3200 configuration
2- You can make the 3200 a local to the 650, but the local configuration like interfaces, dhcp scopes, timezone will not be copied to the 3200 and you would have to configure those manually. You would have to ensure that the 3200 already has the proper licensing ahead of time, otherwise the unlicensed commands that get pushed from the 650 will be ignored.
