Switching to a new server is pretty easy.

First, sync all of your devices one after another, and make sure that all the syncs complete successfully.

Next, take the last one of your devices to be synced (it should have all of the changes), and configure it to sync with the new sync server. Force a sync. The sync will just happen if there wasn't a database already on the server. If there was a database present, you'll get a message alerting you to this and asking if you want to keep the sync database or the device database. Here, obviously you'll want to keep the device database. Make sure the sync completes successfully.

Now you can reconfigure your other devices to sync to the new server. If you like, you can simply reset their database and enter the new sync parameters, and then you won't have to stress over answering correctly for that same question about "which database should I keep, boss?" (note that for all but the first device to be switched, the correct answer is now the sync database).

You'll save yourself a little bit of trouble if you switch one of the Macs first, as you can then just suck over the settings in the sync setup on the iPhone and iPad instead of having to type them all in.
