Install SVN and wiki sw

I bought a second lacie nsv2 I would like to install SVN and WIKI sw
I can do it if I change the original fw nas with fvdw-sl?
If I use a 1TB disk do not need to reflash U-BOOT correct?
I did not understand the difference (but I read quickly the help) between write fvdw and install fvdw
I thnik my correct action is Install.fvdw after erase partitions with fdisk
