Finding old unexploded WWII era bombs: preferred to defuse it in place or move it first?

[A personal note from me, the mad scientist obsessed with zombies:

I don’t even know if I am OP or even posted in this thread. But I remembered it; moreover, thought this news event important enough to search the threads and post after 6 months of absence here, which itself was preceded by years of self-imposed exile from this island.

Huh.]
