Strawberry Bed Question

I have been growing my strawberries in the same raised bed for five years! Do I really have to move them to another area as recommended by the experts? I have planted up new plants from the runners in case I decide to start a new bed.
What would you recommend?

Just don't do what I once did, and move them to where I had recently grown potatoes (same applies to tomatoes)

Verticillium wilt left by the potatoes killed them all
