Because of this, sectors are being massively migrated, which significantly increases cost of storage.
Expected Behavior
Contracts should be renewed by default 2 weeks before expiry without error and sectors should be kept and remain available on the same host.
Steps to Reproduce
No need to take any action. Just wait until a contract is due for renewal.
