You want to change the route of a replicating table so that it can replicate through another named Post queue. In doing so you want to make sure that the earlier messages for that table which are being routed through another queue post before the messages start posting through the new named Post queue.
The following steps need to be performed to ensure that first a reference point is created, the user activity then ceases on the table, and its route is finally changed:
1. quiet the source table
2. Flush from source
3. Activate the new edited config file
4. Once the activation completes, resume user activity on the source table
5. Once the Post processes stop due to flush, restart them
If the queues are backlogged when executing the above steps, one may have to monitor the Post queues for a while before they stop due to flush. At that point they can be restarted.
