Upgrading to 184.108.40.206 is only supported from 220.127.116.11 or later. If you are running a version older than 18.104.22.168, you must first upgrade to 22.214.171.124 or later before upgrading to 126.96.36.199. For customers running on a release earlier than 188.8.131.52 and needing to upgrade to 184.108.40.206 or higher, please contact Delphix support to help coordinate this upgrade.
220.127.116.11 is the last version that can be directly upgraded to, from 18.104.22.168-22.214.171.124.
If you are upgrading from a version < 126.96.36.199 before you begin the upgrade process, contact Delphix Support to perform some pre-checks.
