R77.30 to R80 upgrade

[Atanas_Atanasov]

Hi all

I would like to ask a question regarding an upgrade from R77.30 to R80.10.
I have a working environment with and R77.30 MDS running several CMAs. Each CMA is managing a couple of R77.30 gw, some of which are VSX clusters and other hardware appliances. I need to upgrade all machines to R80.10 but I'm not 100% sure where to start and what might be some underwater rocks I can trip on.

My believe is that I should start by upgrading the MDS to R80.10 directly with CPUSE and then upgrade all the other GWs one by one with the same method.

Is this the right way to go?

Thanks
Best Regards

We were early adapters and went with R80 before having R80.10 so we had to use upgrade export/import on MDS. But I believe CPUSE works now for R77.30 to R80.10. at least it says so in upgrade documentation.

Gateways, both regular and VSX work with CPUSE like a dream.
