    Is replication good between those databases? 

    Get-mailboxdatabasecopy

    You can bypass the restriction, but I would look at the health of the databases first.

    Set-mailboxdatabase -identity <target database> -DataMoveReplicationConstraint None

    Please remove the failed move request and create a new one by adding the skipmoving parameter:

    New-MoveRequest -identity <mailbox> -skipmoving:folderviews,folderrestrictions -TargetDatabase <database>  

    And see if the shared mailbox can be moved successfully.

    Set-MailboxDatabaseCopy cmdlets in the Exchange Management Shell to view and configure database copy settings, such as replay lag time, truncation lag time, and activation preference order. For detailed steps to view and configure database copy settings, see Configure mailbox database copy properties.
