I would expect: yes. But test it thoroughly and/or ask WAGO support.

Hello,

What we have done is we created a backup from running PLC 750-8204 by selecting option "Create Backup"
After creating backup, we tried to download it to our new 750-8204 but it is showing error related to firmware mismatch
can anyone help us how can I upgrade/downgrade the firmware of 750-8204 PLC?

waiting

Firmware is available on request directly at WAGO support. I would tell them about your problem and how you want to solve it. They will give you advise how to solve this.
