Identifying if a Stored Procedure that has FOR Replication is being used

Fellow SQLers,

I am getting ready to move a pub and sub replication to other servers.

I happened to find a sp on the pub db that has FOR REPLICATION in the header.

But when I dump the pub script, I can see only one filter and the filter has similar code that the sp has. The sp is NOT referenced in the Filter. Is likely this is an old/dead sp.

How would I go about validating if this sp is actually being used for replication? I know of no other way than dumping the pub.

Thanks
