Yellow all

I got a few questions for all yee in lore about migration as i am moving house.

I am currently with CPBB butb there serive is dire and i am moving house on the 1st April 2003. I have decided to go with another provider - possible Pipex. Has anyone done; a) a migration? b) a migration to another address?

I am hoping there is a way i can do this without paying an activation fee of any kind. There is also another problem - i may move out again in 6 months so can use the 12 month and free activation some ISPs offer.
