vnsi compatibility (upgrade from gotham => jarvis w/ current vdr backend))

Hi folks,

I'll have a "maintanace window" in to weeks. Due to some itching (and failed add-ons) I want to upgrade my multiple xbmc client + mysql + vdr home installation. Besides the failed plugins and lagging behind xbmc /kodi releases I have nothing to complain. Perfect setup for me.

Most of the time the vdr backend is where I fail. Thus I want to be sure to do the right thing with regard to vdr and vnsi compatibility.

Current setup:
5 x xbmc 13.2 clients (Intel nuc & ASrock V3D Nvidia both w/ OpenElec, various Android 5.x)
1 x vdr 2.0.6 headless server with vnsiserver 1.1.0 and sundtek dvb-c stick (yavdr based)
1 x mysql server (on rpi2)

The two intel based systems are most critical. I use vdr for live TV - no recording and or timeshift. Recording - if any - via vdr-manager

My question is:
Will Kodi 16.1 (or OE 7.0) with its supplied vdr-vnsi plugin (I think it's 1.11.17) work with my 2.0.6 vdr backend and vnsiserver 1.1.0 for basic (live tv) usage?

I might be able to upgrade the vdr backend to 2.2.0 and vnsiserver to 1.2.1, too.

//
Inst vdr [2.0.6-6yavdr0~0.5] (2.2.0-1yavdr0~precise testing-vdr:12.04/precise [amd64])
Inst vdr-plugin-vnsiserver [2:1.1.0~git20140518-7d4aa813cc-0yavdr1~precise] (2:1.2.1~git20150208-f2175ba-0yavdr2~precise testing-vdr:12.04/precise [amd64])
//

Though experience on my side shows that this will be a few ours of additional work ... and I most likely will fail. After that I have another few hour of a new yvdr setup ...

In case I have to do the new backend setup (2.2.0 >) upfront will the exiting xbmc 13.2 supplied vdr.vnsi plugin (1.9.8) work with vnsiserver 1.2.1?

Thanks
