UC520 upgrade from 4.X to 8.6 plus new capabilities

Hi, I we are looking to upgrade a UC520 from 4.1 to 8.X and add some capabilities. Please help with the questions below.

1. Are you aware of any issues with upgrading from UC520 4.1 to 8.X? Does this need to be multi phase?

2. Is the 7942G SSL VPN capability supported with the UC520. If so, Is an ASA required or is there any alternative and better option.

3. What polycom phones are supported with the UC520.

Thank you

UC520 upgrade from 4.X to 8.6 plus new capabilities

1. I have never done an upgrade this far apart... but my guess would be that IOS will be fine (or mostly fine), but I would be really surprised if you did not have CUE issues.

2. Officially -- no (only SPA525G is supported for SSL VPN). Unofficially? I have seen some posts suggesting that it is possible, but have not tried it myself.

3. Officially -- none. Unofficially? Any standards compliant SIP phone can be used if you configure it in command line. Though the functionality may be limited in some ways that SCCP phones are not.
