Use cd card from Raspberry pi4 2 gb. to Raspberry pi4 4 gb

[Gogy1]

Hi, I have Raspberry pi4 2 gb with Raspbian OS installation on it , 32 gb sd card . I received Raspberry pi4 4 gb as a gift . Is it possible just to take sd card from Pi4 2 gb and to put it in Pi4 4 gb.? If yes , What I have to do to transfer the data ( scripts, programs ) from old board to the new one?

Yes you should be able to move the SD card from the 2GB to the 4GB without any problem.

If you move the SD card you move *everything* that is installed on the old Pi, there is nothing stored on the old Pi, it has no inbuilt storage.

However, if you have another uSD card, you could use Raspbian's, "built-in"** , SD card Copier to "clone" the card instead. (Good practice for a basic backup too!) .

you can move (transfer) that microSD card throughout the entire Raspberry Pi board ecosystem...which has microSD slots.

This is one of the reasons why Raspberry Pies are so awesome.
You can easily switch the OS just by switching the SD cards.

I have 3 RPis setup in different places. One is portable. When I want to work in a new location, I just power down the current Pi, take the SD card out, and pop it into the new Pi.
And there you have it - your own roaming profile.

That's awesome! Thank you !

Now another problem . I chenged Raspberry pi4 2g with raspberry pi4 4g. It was set a web server with weather site on it. When I moved the old cd card to the new device , I saw that the raspberry pi4 4g use now new IP address . What can I do to use my old web server and old my data on it .? Is it possible? Maybe i have to set everything from the beginning ?

There are several solutions.... If the other machines are set up correctly, you can access the Pi by hostname. Or you can set up the Pi to have a static IP address (then the IP address will move the SD card). Or you can assign a reserved IP address in your router, but you'll have to change that if the Pi is changed, as it will go by MAC address.

If you move the SD card you move *everything* that is installed on the old Pi, there is nothing stored on the old Pi, it has no inbuilt storage.

*Minor* correction... Pi4Bs have a writable EEPROM bootloader (and, for that matter, PCIe to USB device firmware). That *may* be different from one Pi to another, depending on how you go about keeping your Pis up to date.

Everything is working now on the local web server with the new ip and the new Raspberry pi 4 4gig. Now maybe I have to assign the new ip to my domain name , so i will have the site in the internet . Is it right?
