Migration from RN104 to RN426

Last night I upgraded my reliable old RN104 to a RN426. I thought it would be worthwhile documenting what happened for future reference. In short everything went quite well, but with a few issues that could have caused some problems. 

The good: I unpacked the 426, what a lovely looking thing. First thing I did was put a single old drive into it, connect it to my network, and upgrade the firmware to the latest version - more importantly the same version as what the RN104 was running (6.10.3). Then I took a quick copy of my config and held my breath....

... shutdown both devices gracefully. I then took drive 1 out of the 104, and placed it into bay 1 of the 426 (that's the top one FYI), and proceeded to do the same for each disk. Then I turned it on. After a couple of minutes booting the new 426 is on my network, all my shares are back, users, name, everything! Awesome! 

The less good: after happily checking shares, etc I notice one strange problem. All of the icons for the "featured apps" and Apps themselves are showing as broken gifs, and I couldn't install any of them. Weird. I was very careful to make sure I wasn't running any aps on the old 104 after reading that could cause problems here (sorry - can't find the posts). After a little more digging I found this:  //community.netgear.com/t5/Using-your-ReadyNAS-in-Business/App-icons-in-web-interface-broken/m-p/1322928 Very close to the same problem I have. 

So time to brush off my linux and dig under the hood. First I had to enable ssh access on my new toy. This article helped: kb.netgear.com/30068/ReadyNAS-OS-6-SSH-access-support-and-configuration-guides 

Then I tried what was listed as the solution in the above linked post. I was getting a similar error in the startup of apache2, but like 

@ NesporBellisRM  I was getting a "Cannot load /usr/lib/apache2/modules/libphp5.so into server: /usr/lib/apache2/modules/libphp5.so: wrong ELF class: ELFCLASS32"" error 

I had already tried the  "apt-get update" solution suggested, and rebooting, and... well you get the idea. In the end the fix seemed to be to run: "apt-get install libapache2-mod-php5" as root. It did say that I was running a modified php.ini file and did I want to replace it. I chose to leave it alone.... and so far so good. The icons are back, apache seems to be working, and I can run Apps as intended. 

Not entirely sure why my shiny new RN426 needed such open-heart surgery, but I guess it's because I moved the disks from the old 104. Of course for a complete linux newbie doing ssh,apt-get, etc would possibly be a show-stopper. 

Hopefully this helps someone in the future. And if anyone can see an issue with what I've done please let me know!
