ADX Studio - Migration from CRM 2013 on premise to Dynamics 365 online

Hello,

We have CRM 2013 on premise with ADX 7.0.0017 we would like to migrate to Dynamics 365 online

Is there a documented procedure / best practices how to migrate ADX solution and ADX entities data?

Is our current version good enough for Dynamics 365?

Do we need to upgrade before the migration?

We use Rewrite URL for our pages - is it compatible with Dynamics 365?

What is the best practice to migrate the data?

Thank you,
