Hi @mongloz,
Here are some guidance for migrating SharePoint Server to a new domain, please take a reference to them:
- Migrating SharePoint 2013 Servers to new Domain (Same Version and Build): Best Practice
- Migrating sharepoint farm from one domain to another
- How to move SharePoint servers to different domain (new AD) without losing the data integrity with limited time and effort?
Generally, we migrate a SharePoint farm via backup databases and attach them to a new SharePoint farm. Workflows may need to be reconfigured to ensure they function correctly in the new domain. This may involve updating any URLs or permissions associated with the workflows. Also, be aware of any domain-specific settings that may need to be adjusted, such as service accounts and permissions.
