Migrating Theme Coded CPT to Metabox and others

Hello

I am using the chipmunktheme.com and it comes with a CPT called 'Resources' built within it
Since the theme isn't properly coded, I am trying to move to a different theme, Generatepress

1 I want to move the CPT to Metabox, I installed the ACF migrator extension and I didn't see the 'ACF Migration' option in the admin menu of Metabox. I am assuming it is because the CPT is coded into the theme

How do I move to Metabox in this case?

2 The CPT also made the URL this way https://domain.com/resource/post-name
I used a code from the internet to make it https://domain.com/post-name

In Metabox is there a way to remove the /resource/ part of the URL or do I have the use the code?

Thanks
