I am looking for any and all advise regarding upgrading a clustered pair of 5800 series appliances from R80.20 to R80.40. I am just beginning my search for documentation, procedures, and other experiences doing the same. While I am basically fishing for experiences performing this upgrade and what kind of things to look out for I welcome all links to documentation or blogs that may be useful.
Questions and Concerns:
- What features have caused you trouble while upgrading from R80.20 to any other version?
- Do you have a preferred upgrade method? Why?
- Does upgrade path help or should I just rip off the band aid and go straight to R80.40?
