How to migrate a Mac Pro (Mid 2010) to new Imac 5k

[thetoness]

Hi,
I am seriously thinking about getting a new Imac 5k. I presently own a Mac Pro with an 256 SSD (boot) and 3 2tb hard drives. the 3TB fusion drive will be more than enough storage for me on the Imac 5k.
Since there is no target drive mode on the Imac 5k, what is the best way to migrate from the Mac Pro to the Imac 5k.
The Mac Pro only has Firewire 800 and USB 2.0 ports. Would it be best to get a Firewire to Thunderbolt cable?
Any help you can provide would be helpful.

I have everything backed up to a NAS Synology 1501

I think you can use an ethernet cable and do it even wireless.
I haven't done this yet, though.
