Changing Domain of SharePoint Servers

Below are some quick list of steps you might need to take to change the domain of a three server farm from one domain to another.

Note : Please take proper backups before proceeding.

SQL1 : SQL server
Web1 : Web Server
App1 : Application server

1. Create a SQL mixed mode (SYSAdmin/Security Admin)account.
2. You will need this account to login to SQL after it is unjoined from domain and rejoined to new domain.
3. Web1 : Run config wizard to unjoin the server from the SP Farm.
4. App1 : Run config wizard to unjoin the server from the SP Farm.
5. SQL1 : Unjoin and re-join the new domain
6. Web1/App1 : Add servers to the new domain.
7. Create new SPFarm account with Sysadmin or dbo role on SP config/admin databases and all content databases.
8. App 1 : Run config wizard to join to existing farm and choose the SQL1
9. Web 1 : Run config wizard to join to existing farm and choose the SQL1
10. Login to CA and web Applications with the farm account and verify all accessible with the new account.
11. If your company is specific about using different accounts for App Pool, Service Apps etc, please add new accounts in the managed accounts and assign accordingly to the pools or svcapps etc.
