So, I've seen that bulk rename of nodes isn't available but there are some kludges / workarounds that I have seen. Not keen on using any of those right now as it means diving into the database.
My query is relatively simple, I guess.
I have a node that is discovered as, say ABC_123. If I edit that node and rename it to: Prefix-ABC_123 will that rename remain after a re-discover operation or will it default back?
It will stick as long as its only the Caption field you are editing.
