I have successfully performed storage migration on standalone chain. But how to do this for parachain ? Like, How/what wasm should be upload of new version and Where Should I upload ? Is there any different process from standalone to do this ?

If I'm simply upload the upgraded wasm, the blocks remains finalising but sudo.sudoUncheckedWeight ready : enter image description here this process will not complete. Can anyone please help me to solve this problem ?

Thanks in advance !!

what you want to do is use the sudo tab, then sudo > setCode(WithoutChecks)
