Upgrading all these to 2.0 is a bit of a scary thought.
I - and I'm sure others - would appreciate input from anyone who has already converted a custom module to work properly with 2.0. It's early days given that 2.0 is not even in beta, so I hardly expect many people have. However, people can always add to this discussion later.
I'd like to know (a) about timescale [converting a simple module took X hours/days/whatever, converting a more complex one took Y] and (b) about difficulty - i.e. does it work almost 'by rote' so that we could get less experienced developers to do it by following a wiki page - there doesn't seem to be a single one yet, or I couldn't find it, but I guess there will be - or did it require many complicated decisions about new approaches, or something in the middle.
The reason for this is so that I can give my employer some idea of how difficult we're expecting the conversion to be. At present, I'd say my expectation is that module changes will be significant but not too bad, while dealing with our changes to core (deciding some are no longer necessary, re-implementing others) is probably more serious.
