STORAGE SPACE - Rasp Pi4

Hello everyone.
Ever since the new Umbrel update I’ve noticed that in order to run Electrs I have to keep a complete copy of the blockchain on my storage. I currently have 200 GB of storage left of 1TB. MY question is, has anyone been able to add another 1TB SSD without starting over or is it just plug and play? Im using a Raspberry Pi4. Thanks in advance!
