Initially, MISO is not changing the XML API used for updating availability.  MPs can continue to use the one deployed as part of MCS and all updates will be reflected in DSRI.
The XML API for availability in CCE is at:
https://cce.midwestiso.org/mcs/ws/lmr/sendAvailability
and the API updates will be visible at:
https://cce.midwestiso.org/dsri/availability
(as well as in the MCS web interface).
