The only promise I can't make - though there's a high chance it will actually be possible - is that you won't have to use the ISO at all for upgrading to the final release.

I also noticed that I get an option to "Upgrade" to RC1 from beta 2. This should technically not happen since I installed beta 2 in Legacy BIOS mode and am now installing RC1 in UEFI mode since the former would be deprecated.

Is that an error in installer or upgrade is possible ?

It's not exactly an error, but it's not very good either. This would fail at some point so don't attempt it. We suggested to add the detection of such situations, upstream, but neither them nor us had the time to implement it: https://github.com/xenserver/host-installer/issues/11
