We are doing cross forest migration using QMM for AD. I have a concern related to the bullt in groups “domain admins” and “domain users”  that we are not migrating and making sure that the users who were in those groups in the source and once they are migrated they don’t lose access to the resources. We won’t be migrating those groups to the target. . What is the best tool to use to analyze permissions? How do you usually re-assign permissions in the target for those built in groups? What is the simplest and best approach here to ensure the access to resources after the migration.

We won’t be migrating those groups to the target.  You can't have them and not migrate them..

Built-in accounts (such as Administrators, Users, and Power Users) cannot be Active Directory Migration Tool (ADMT \ QM) migration objects. Because built-in account security identifiers (SIDs) are identical in every domain, migrating these accounts to a target domain results in duplicate SIDs in a single domain. Every SID in a domain must be unique. Well-known accounts (such as Domain Admins and Domain Users) also cannot be ADMT \ QM migration objects.

If you want to migrate domain admins and domain users, you need to use SID mapping file for migration and with ADMT you can use security translation wizard to translate security on shares, NTFS security on already migrated servers but you can't simply migrate those groups
With security translation its possible to replace source domain admins \ domain users with target domain admins \ domain users

I don't know if this feature is available with QM, please check
Below post shows how to create SID mapping file and do security translation for built-in principles with already migrated objects
http://blog.thesysadmins.co.uk/admt-series-10-security-translation-wizard-local-profiles.html

With ADMT,
1st migrate server with standard ADMT computer migration wizard
After that use above method to translate built-in accounts security
