We do not provide migration script for netgroups however it is very
simple to create a script that would recreate netgroups using IPA
command line.
The reason why we do not do netgroup migration automatically is because
it is a good time to reconsider now netgroups are used in your environment.
For example if you use netgroups to group hosts we recommend you
creating a host group for those hosts. Each host group by default has an
automatically created netgroup with the same name. This can be turned
off but out of box every host group creates a netgroup.
If you use netgroups for users consider switching to user groups rather
than using netgroups for users. Using user groups is more flexible and
preferred method.

Also see chapter 7. It has examples of the scripts that can help you to
migrate netgroups.
