The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

I have the below query that works fine in non prod env while it throws above error in prod

 SELECT 
CASE WHEN MSP.filecreationdate NOT LIKE '%T%' THEN CONVERT(INT,CONVERT(VARCHAR,CONVERT(datetime,MSP.filecreationdate),112))
            ELSE CONVERT(INT,CONVERT(VARCHAR,CONVERT(datetime,substring(MSP.filecreationdate,1,10)),112)) END
            FROM STAGING.dbo.cobenrollxmlMSP MSP
