Setting up new ShivaPlug

[AllenMcw]

Hello,

It looks like my few years old NSLU2 has died - wont' even power up anymore so I'm looking at replacing this with ShivaPlug.

I've seen the FAQ on setting up new ShivaPlug: http://wiki.meteohub.de/Setup_SheevaPlug

I had not done a backup on Meteohub before this happened. Will this cause me problems when trying to set up my new ShivaPlug?

Will the fact that my old NSLU2 is no longer accessible cause me problems in transferring the license to the new ShivaPlug?

The FAQ mentions that 4GB SD card is recommended for ShivaPlug but these are hard to find now. Will 8 or even 16GB work as well?

Anything else I need to be aware of?

I actually need to order the ShivaPlug so unfortunately I won't be able to complete this for some time until the new unit has been shipped to me.

Thanks much
Allen
