Maybe clonezilla?
Both the SD cards and SSDs are interpreted as block storage devices by the Linux kernel. You should be able to clone the SD card to a SSD with tools such as
dd.Why dd over rsync?
ddis transferring in blocks whilersyncis transferring in files (or file tree). If you wanna clone a disk, the former is a better option as you want a clone and a block device may contain more than one partition.
I think using dd is the way.

Raspberry Pi4? Then yes, here’s a guide to update your bootloader:

For older models(Pi<4), no but kinda: Afaik oder models could only boot from SD-cards. But that only means the bootloader has to be on the SD-card. So you can copy everything but the bootpartition and change the entry in the /etc/fstab to the new root on the SSD.

Im not 100% if that changed or not, but if you are using raspberry pi I think you still need sd card to boot from SSD. The way you install it is actually installing OS on both of them and then doing some tricks to boot from USB after initiall boot from SD card. Once you start your OS you can unplug SD card, but still need it for next reboot. Maybe there is a good way how to clone, but deffo not simple as regular cloning.
You can just add SSD as a storage and move docker volumes and catch folder to it (not sure about omv tho), but that wouldnt move your OS.
Many SSDs failed on me, but never SD card in raspberry pi. I do use high quality cards tbf and Im aware SSD is much better for OS, but feels like its all about luck. Just my 2c
Use dd on the entire disk?
