Change Existing domain of SharePoint 2019 Farm

We have existing SharePoint 2019 Farm 2 APP Server and 2 WFE server with SQL Server Always On and 2 web applications and custom farm solutions deployed and custom workflows are published.
Now we have a requirement to change the SharePoint Servers A.D Domain, here also SharePoint Servers move to new domain.

-In this case what is the best practice to up and running SharePoint Farm and Web Applications
-Is it require to create new SharePoint Servers in New Domain and create SharePoint Farm? or in same SharePoint servers can I create new SharePoint Farm after SharePoint Servers changed to new Domain Controller?
-Is it also require to create new SQL Server cluster with Always on in new Servers?

If we use existing SharePoint Servers and change domain controller and after create new SharePoint Farm is custom workflows and custom farm solutions will work or not?
