From 73764d0dd2c0a457b7f438f003b4dbc6b94a65e3 Mon Sep 17 00:00:00 2001 From: Gua00va Date: Mon, 31 Jul 2023 23:51:39 +0000 Subject: [PATCH] Deprecate `exchangeTransitionConfiguration` functionality (#4517) ## Issue Addressed Solves #4442 ## Proposed Changes EL clients log errors if we don't query this endpoint, but they are making releases that remove this error logging. After those are out we can stop calling it, after which point EL teams will remove the endpoint entirely.
