IANAL, but as long as the data is currently being released as
CC-BY-SA, then there is no breach of the CC license.
CC-BY-SA only stipulates that the data, when published, must be under
CC-BY-SA. It doesn't say that you cannot enter contracts promising to
release the data *in the future* under another license.
If the data will be released *in the future* under a different
license, then it's true that the CC license is breached.
But, in the case of OSM-ODbL, assuming that all the ODbL rejectors' IP
will be removed before the actual relicensing, since what remains is
the IP of all who have agreed to the CT, then it's like everyone
mutually agreed to relicense their own data under a new license, thus,
not breaching the CC license.
