No, that is not possible. Please review the documentation here:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.0.0/bk_ambari-upgrade/content/ambari_upgrade_guide.html

Important:

Ambari 2.7 only supports fully managing a HDP 3.0 cluster. If you are running any other HDP version, you must first upgrade to HDP 2.6 using Ambari 2.6, then upgrade to Ambari 2.7 and use it to upgrade your cluster to HDP 3.0. Not all cluster management operations are supported when using Ambari 2.7 with HDP 2.6. Please see the next section for limitations.

You need to upgrade in pieces. HDP 2.3 is very very old.

Best option is to setup a new HDP 3.0 cluster and distcp your data over.

Otherwise you are doing

Ambari 2.0 -> 2.1 -> 2.3 -> 2.4

HDP 2.3 -> 2.4 -> 2.6

Possibly more jumps.

Then Ambari 2.6 to Ambari 2.7

Then HDP 2.6.5 -> HDP 3.0
