Last week I had my ADSL activated following a changeover from ISDN. Friends who've done this through BT have had a nightmare, so I was braced for the worst...
...And? The engineer converted the line, I rang to let Plusnet know, and that was it. Done.
No problems ( apart from a knackered router, but that's another story).
I just wanted to say thanks for the smooth conversion, I lost an hour's online time at most!
