I've different versions of Raspberry Pi's and want a set of different software on all of them. I made sd-card images and that works fine as long it's the same version of a Raspberry, but when the version is different, the image won't even start.
Is there a way that that I can use a set of software (VPN server, Webiopi, Gspread etc) copy to another Raspberry, without installing and setup each and every program again?
