[Hosting]

Im new with netapp systems  I'm having a problem to monitor an old storage system.

Storage version 7.3.3   7 mode

im using :

NAbox 2.4.2 (2017-12-28).

NMSDK 5.7.
Harvest 1.4.1.

"Update of system-info cache DOT Version failed with reason: Version 1.14 was requested, but only 1.12 is supported."

Does anyone know if there is a way yo fix it?
