I followed Abu's guide for manually restoring settings from images older than 4.2 and it went extremely well. However there were a couple of places where I had to deviate from the guide as follows :-
1 I have a wi-fi network and so when it came to the wizard running after flashing the new image, I allowed it to run cancelling the restore and scan prompts until the network wizard appeared at which point I entered the settings and connected the box to my network.
2 When I used PuTTy to connect I got a security alert :-
Question - is this message a direct result of the upgrade to 5.0.017?WARNING - POTENTIAL SECURITY BREACH!
The server's host key does not match the one PuTTY has cached in the registry.
This means that either the server administrator has changed the host key,
or you have actually connected to another computer pretending to be the server.
I used TelNet instead and issued the init 4 command from there.
3 When it came to restoring plugins the commands
for installing the Samba plugin failed so I used the Menu > Setup > System > Network > Samba setup.opkg install packagegroup-base-smbfs-client
opkg install packagegroup-base-smbfs-server
Incidentally, the commands now work since the plugin has been downloaded via the menu.
I do not have cams installed so could not use that part of the guide.
I had a quick check and everything seemed ok so I did a settings backup.
Thank you very much for the guide, Abu.
