Yes, the timing is a bit unfortunately with respect to wikimania. On the other hand, the whole OSM license change process has been dragging on for years now draining resources, so it is imho good that it is finally soon coming to an end.
The redaction bot has now begun with its edits in Ireland.
One can see the edits it is performing under the list of edits of the account "OSMF redaction account" ( http://www.openstreetmap.org/user/OSMF%20Redaction%20Account/edits)
Also one can watch general OSM editing activity including the redaction bot with a little java program from http://gpsmid.sourceforge.net/misc/LiveEditMapViewerJ-redaction.jar
Given that the bot has started already, overall it is only about 1% and it will draw over an extended period of time, I am currently leaning towards the first option too.
I.e. I have not stopped the diff importing process on the toolserver and thus all new edits, as well as all deletions from the redaction process should show up in the wikipedia OSM maps within about 15 minutes.

The timing couldn't be worse. The Wikimania is starting now and I want to use this event to promote OSM and WIWOSM. But we can not change it.
So I prefer the first way to be up-to-date with WIWOSM.

Hello everyone,
After OSMF was originally wanting to start the license change at the beginning of April, due to technical problems with the redaction process of non relicensed data, it has been delayed till now.
The OSMF has now announced a new schedule [1]. It will begin removing data for which it does not have permission to relicense from CC-BY-SA to ODbL 1.0 this coming Wednesday 11th.
It will happen as a slow process while normal editing of OSM data continues. From a data consumers perspective the removal will look like any normal deletion of data and will be mixed in the minutely / daily diffs with the normal changes. The duration of this process is not yet clear due to the uncertainty caused by the load of the normal edits, but very rough estimates supposedly range from a week to several months, but hopefully it will be completed within a month.
Luckily, worldwide only a little more than 1% of the total current data has to be removed, but regionally this can unfortunately still be a lot more despite all the efforts to minimize the impact.
The question now is how should the wikipedia osm-tile-servers handle this situation?
- continue as normal, importing the minutely diffs. This has the
advantage of staying up to date with all the ongoing mapping efforts, but the disadvantage of degrading the data in areas where the redaction-bot deletes things.
- Suspend the diff imports during the redaction phase: This allows
mappers time to fix some of the damage done during the process, but removes the up-to-dateness of the map.
This affects at least the tileserver run on toolserver.org which serves tiles for the osm gadget for various wikipedias and the WIWOSM project. But depending on when the new tileserver run by the foundation for its mobile project goes into production, it would also need to make this decision. I don't currently know how the mapquest open tiles will handle the situation.
During the redaction period, all data continues to be CC-BY-SA. When the actual cut-over to ODbL will occur is not yet clear, as the timing of the redaction bot is still uncertain but presumably very shortly after it has finished.
