kims Posted November 27, 2013 Share #2 Posted November 27, 2013 Hi Has anyone tried this from 4.3 and down to 4.2-3211 ? I tried the mentioned method, but I wont get the "install" option when right click the entry in "Synology assistent". Is there a way to force it, I dont mind to reformat and start over? Best regards Link to comment Share on other sites More sharing options...
k0ste Posted November 28, 2013 Share #3 Posted November 28, 2013 You need a Synology Migration. Install your hdd's to another hardware (for DSM understand - it's another hardware, I don't know how it as determined, may be by MAC adress), boot from flash and install XPEnology, after this go back to your hardware and install 4.2. I'ts a simple and fast way, i think. P.S.: use web browser for upload, not SA (bugg's), and don't save any settings, because it's don't support downgrade.

fonix232 Posted November 28, 2013 Share #4 Posted November 28, 2013 You can try a settings backup, that *should* be able to import stuff after losing the configuration. Unfortunately there's no built-in option to save apps, their data, etc. Maybe that's the big thing in 5.0? Link to comment Share on other sites More sharing options...
kims Posted December 22, 2013 Share #5 Posted December 22, 2013 Hi Thx for the reply. Sorry for the late response. I got sick, and was out of circulation for a while, but now I am back I am not familar with the "Synology migration" and "XPEnology". What do you mean with "install your hdd's to another hardware"? Could you be more specific of what to do ? - do I have to format the disks on a PC for example? - or should it be another NAS of same model? best regards, and appreciate your reply Link to comment Share on other sites More sharing options...
k0ste Posted December 24, 2013 Share #6 Posted December 24, 2013 Just put your hdd's from your system to another, install XPE. Put hdd's back to your system, install XPE. Profit, all data saved. Link to comment Share on other sites More sharing options...
