> The Coretime Chain was deployed on Kusama and with the enactment of the runtime upgrade 1.2.0 yesterday, the attempt to migrate from the leases from an auction model to coretime failed. During the transition to coretime, the relay runtime upgrade attempted to migrate leases using XCMs, which failed due to insufficient weight, preventing the migration. More details can be found [here](https://github.com/polkadot-fellows/runtimes/pull/276).
> 
> We’re working on a fix (see link above) and will push a runtime upgrade soon, so that all leases are secured for a smooth migration. We will keep you updated on further steps.

There is a postmortem for the failed migration [here](https://forum.polkadot.network/t/kusama-v1-2-0-coretime-migration-xcm-failure-a-postmortem/7536)
