Upgrade Spokes from 2.7 to 2.8

Hello,

We're currently using Spokes SDK 2.7 in our software. We plan to upgrade to 2.8.

Some questions:

1. Is 2.8 fully compatible with 2.7? Namely, after upgraded, our software should work the same way as before without changing any code, correct?

2. I suppose 2.7 and 2.8 can't co-exist in the development machine, please confirm.

3. Should I just go ahead to install 2.8 on top of 2.7 in the development machine? Or should I uninstall 2.7 first?

4. In run-time, we look for the registry to check the presence of Spokes:

HKEY_CLASSES_ROOT\CLSID\{F9E7AE8D-31E2-4968-BA53-3CC5E5A3100A}\LocalServer32

HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{F9E7AE8D-31E2-4968-BA53-3CC5E5A3100A}\LocalServer32 (for 64bit)

Will 2.8 use the same entry or a different one?

Thanks in advance.
