Upgrade from hassos_rpi4-64-5.1 to hassos_rpi4-5.3

I installed rpi4-64-5.1 some time ago to be able to install HassOS to an SSD and boot from it on an RPi4 4GB. I have SSH setup through Putty. Should I be able to upgrade by sending the following in an SSH session? Does it automatically know that it needs to be 64bit? Is there anything else I should know other than making sure I have a recent snapshot?

ha os update --version 5.3
