Upgrading Idrac on R630

Hi,

I have lost my connexion to the server console via the idrac's web access.

I saw that this problem can occurs when the idrac version is to old comparing to Java.

It may not be the real problem but i saw that i can update my idrac (v2.30.30.30 to v2.80.80.80).

My question is, does it require an upgrade path or can i update it without risking to loose anything ?

I've searched a lot on dell's forums or dell's documentation but i didn't saw this information clearly.

SPEC:

- ESX 6.0.0 build-3620759

- BIOS: 2.1.7

- lifecycle 2.30.30.30

- IDSDM 0.15

- microsoftware 2.30.30.30.

 

Thanks for your attention,
Best regards.
