you have to reinstall completely. BUT

- make a list of installed ports
- make backup of all configuration files and data files
- install FReeBSD/AMD64 AND this ports
- THEN put all your config files and data files.

and then it should work fine. and there is noticable speed difference 
compared to i386.
