According to ICANN’s rules and regulations, expired domain can be transferred to another registrar. Expiration or non-renewal of a domain is not a valid reason to decline any transfer request. An expired domain can be transferred to another registrar while it’s in the expiry grace period.
As per ICANN rule, you must complete the transfer process within the grace period and before it falls in the “Redemption” Grace period varies based on the domain extension.
