How do I update the SDK without VCC?

I cannot use VCC because I am running Windows 8 and VCC will not launch on Windows 8 (Windows 8 does not support Microsoft Edge).

How can I update the SDK on my avatar to the newest version without breaking my animator states, physbones, and the descriptor? I know that there is a template project, but when I import my avatar into that, all the VRC components break.

My avatar is using the latest SDK before the move to VCC, “VRCSDK3-AVATAR-2022.10.27.00.35_Public”

Thanks!

No idea on project migration, but you can make a new project using that template and then copy stuff to it. Copy everything out of asset except the old SDK and see what happens?

Edit: I just noticed a small mention of the template, what sort of details can you share of it break?
