Can I use the existing 1/1/4” pvc pipe to fit 200amps rated wires,

[Alexwheel]

I am doing a 100 to 200amps (underground) service upgrade.
Can I use the existing 11/4” pvc pipe to run the 200amps rated wires?
What is the smallest size of wire I can use for the 200amps?

Is (2) #2/0awg copper & (1) #6awg neutral copper ok?

What is the length of the service cable you are upgrading?

2m from meter to breaker panel.

This thread might be better placed in the Canadian subforum as the practice here in the UK is different.
