R Pi 1TB SSD - - > 2TB?

I’m running Umbrel on a R Pi with a 1TB SSD. In addition to a Bitcoin node I’m running a number of other applications. My Bitcoin node is crashing due to running out of disk space.

What is the easiest way to solve this problem, swap the 1 for a 2TB SSD or add another 1TB SSD?

I think the best solution is to replace the 1TB HDD with a 2TB one.
If you’re using a Raspberry, the operating system and apps live on the SD card.
I suspect the blockchain is the one asking for more space.
However, it would be a good idea to check the status of the SD card and its capacity.

What would be the best procedure for moving everything from a 1TB SSD to a 2?
