Don't quite understand DSM 6.0 ARM7 instructions

[mightyoakbob]

I'm trying to decide if it is safe to upgrade my NAS Synology DS214+ (ARM7) to DSM6.0. I only use two Packages: Minimserver and BubbleUPnP. I've therefore been reading the instructions without being able to see DSM 6.0 and probably being a bit thick too so there are some little things I don't quite understand.

It is the installing java bit that is making be unsure. References to a 'main menu' confuse because I don't know of anything that FOR ME fits that description. Do the instructions there mostly refer to the package center?

Is it obvious where I get Synology java 8 from?

Does the 'upgrade java button'
1. exist in the package center?
2. link to the download website?

Thanks for any advice, I just like a clear picture of what I'm taking on *before* I commit to it.

Cheers,

Bob.
