Is there any easy way to migrate from aws x64 to arm arch? like without configuring a new arm based server and installing packages and file? it is currently running with Amazon linux AMI, we wish to change it to Amazon linux AMI 2.
I just wanna know if there is some tool/method to proceed with this.
You can't do that. X86 code doesn't run natively on ARM, nor vice versa. You must create a new instance and migrate any data you wish to migrate.
