Can we upgrade from Harvest 1.3 to 1.6 directly

[Pranjalag]

Hello All,

Can we upgrade directly to Harvest 1.6 from 1.3 , As we are getting following errors upon the Clusters running upon Ontap 9.6 
Cluster1 - NetApp Release 9.6P3
[2020-04-15 02:10:01] [WARNING] [sysinfo] Update of system-info cache DOT Version failed with reason: in Zapi::invoke,

cannot connect to socket

Cluster2 - NetApp Release 9.5P8
[2020-04-15 11:11:21] [WARNING] [sysinfo] Update of system-info cache DOT Version failed with reason: Server returned HTTP Error: 400 Bad Request

I also tried to rename and add one entry for the respective ONTAP version over "/opt/netapp-harvest/template/default/cdot-9.x.x" but it didn't helped , In case if upgrade is required kindly share the KB article for the steps.

Can you check the version of NMSDK you are using ? You might have to upgrade it.
