How to bring down the items left waiting either backup or indexing to zero ?

Hi People,

I'd like to perform CIFS share migration from the existing NTFS drive, but when I execute the SQL script to check the number of item stuck in waiting mode is almost 1 million ?

USE EVVaultstore1
SELECT COUNT(*)
FROM WatchFile 

So how can I bring down that number into 0 safely ?

I have set the Index and Vaults to be in backup mode since yesterday but the number is not decreasing ?
