The migration from MIDL.dev to the new sequencer operator is expected to take place around 8AM BST (following a successful vote by Tezos bakers). MIDL.dev will halt block production 5 minutes ahead of the migration, and the new operator will resume it a few minutes after the migration. The migration will be transparent for the node providers (no manual intervention is needed except for upgrading their nodes to v0.35 or higher)
