@Trudy: How sure are we that we may not require this registration when ever any patch is updated?
I mean we all do all kind of Integrations (2nd or 3rd Party), OTA & couple of other things where this can be helpfull over the issue FIX perspective & I personally suggest to go for a complete Client Registration when ever any patch update.
Mention any if this sems to in appropriate.. (Just to be in Safe Hands)..!!
