About endpoint ACLs and network security groups for classic VMs

I'm trying to change the functionality from endpoint ACLs to network security groups in order to migrate classic VMs to ARM.
In this case, after the network security group settings are completed, will the endpoint ACL settings become invalid when they are associated with the subnet? Will I still be able to use endpoint functionality unless I remove the endpoint ACL?
I asked this question because I wanted to migrate the ACL settings little by little.

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you would like to migrate to classic NSG from ACLs in existing Azure classic VM.

    NSG and ACL co-existence is not supported in classic VMs.

    In case you would like to attach a classic NSG to the VM, you must make sure the ACLs are removed from the endPoint.

    This means, there is no concept of one being preferred over the other.

    Thanks,

    Kapil
