Hii,

I am working on unity migration projects in 64bit arm, Actually I have made my project in 2017.4.12f1, In this there no option in project setting for arm64 and I can’t migrate my other updated versions which have arm64 option in player setting. There is any way how exiting project support arm64 bit.

Anyone please help me.

You need to upgrade to at least 2017.4.16.
