Update to DSM 4.3 on Synology DS211+?

[Siriuslux]

Hi,

I am running Minimserver 0.72 on my Synology NAS, presently with DSM 4.2-3211.
The Java Engine is Java SE for Embedded 7 1.7.0_21-0015 by patters and BubbleUPnP Server 0.6.5 by winxi.

I am wondering whether I should be updating the DSM to 4.3, I am hesitant because I do not know which components I would potentially have to reinstall after the update, knowing that the initial installation took me several attempts and hours to finally run smoothly.

Can anybody give me some hints?

BTW: as stated in other threads I am streaming to an Oppo BDP-105 using Kinsky.

Thanks in advance,

Joerg
